| 47819 3N68LE00 Return | 2GB file size limit of datalog files The maximum size of datalog files is 2 GB. Workaround: N/A
| |||||
| 48016 3P7CBB4Q Return | Unsigned int32 loses value in formula node when you write to the most significant bit If you wire a hex value greater than x7FFFFFFF as an unsigned, 32-bit integer to a Formula Node, LabVIEW coerces the value to 0. If you use a negative number for U32 input/output variable, LabVIEW will coerce the value to 0. Workaround: 1. Use the Mathscript node or LabVIEW code for the operation that involves an unsigned, 32-bit integer.2. Use signed 32-bit integers instead of unsigned 32-bit integers in the formula node.
| |||||
| 50420 44CG88SN Return | Update the Pulse Transition Measurement Express VI The terminology and measurement definitions for the Transition Measurements VI comply with IEEE Standard 181-2003, IEEE Standard on Transitions, Pulses, and Related Waveforms. However, the Timing and Transition Measurements Express VI does not comply with this IEEE Standard. Workaround: The Slew rate refers to the transition slope. The Preshoot refers to the pre-transition undershoot (rising pulse) or the pre-transition overshoot (falling pulse). The Overshoot refers to the post-transition undershoot (rising pulse) or the post-transition overshoot (falling pulse).
| |||||
| 51185 47FGSQCS Return | Cannot save VI as the same name as missing library member VI If a library contains a VI and the VI is missing, you should be able to save a VI as the same name as the missing VI in order to rebuild the missing VI. Currently, LabVIEW does not allow this. Workaround: Delete the item from the library, save the new VI as the same name as the missing VI and then move the VI into the library.
| |||||
| 51311 477DKPBQ Return | LabVIEW does not maintain child-only item setting when dragging an item within a tree If you have a tree item with the child-only setting, and then drag it within the tree, LabVIEW loses the child-only setting. Workaround: Use tree events to (1) get the child-only flag setting when the user begins a drag, and (2) reset the child-only flag after completing a drop.
| |||||
| 52027 4A4GRP00 Return | Cannot use the 'New>>VI for Override...' dialog to create override of password-protected VI unless you have the password You use the 'New>>VI for Override...' dialog to override an ancestor VI in a LabVIEW class if the VI you want to override is password-protected. Workaround: Make a public VI which wraps the functionality of the private VI, and instruct others to override the public VI.

| 119444 Return | Multi-column listbox format lost on upgrade A Multicolumn listbox created in LV 7.1 may lose its format when opened in LV 8.5 or later. Column headers lose their 3D appearance and font formatting might be lost. Workaround: Replace the Listbox and recreate all customizations
| |||||
| 120686 Return | Write to LabVIEW Measurement Files (LVM) using Express VIs takes up a lot of memory The "Write to Measurement File" Express VI consumes a large amount of memory when writing to a Text File (LVM). However, the memory usage is smaller when the same Express VI is used to write a TDM/TDMS File Workaround: Use general LabVIEW VIs (and not Express VIs) to perform an LVM write for large amounts of data. The other option would be to write in smaller chunks.
| |||||
| 51179 47B12U5U Return | Error 6 occurred at Create Folder in Create Directory Recursive.vi when building an application (EXE), shared library (DLL), source distribution or web service When building a Build Specification, the build process fails with Error 6 at Create Folder in Create Directory Recursive.vi. This usually happens if the path one of the files generated by the build (temporarily during the build process or as part of the output) is too long. The operating system requires paths for files to be less than 255 characters. Workaround: 1. Use a shorter path for your build destination (i.e. c:\build\) and if necessary copy the output to the final location you need.2. A. For application (EXE) and shared library (DLL) build specifications, place a checkmark in the Use LabVIEW 8.x file layout checkbox on the Advanced page of the Properties dialog box.2. B. For source distribution or web service build specifications, uncheck the Preserve disk hierarchy checkbox on the problem Destination on the Destinations page of the Properties dialog box.
| |||||
| 141699 Return | NI Distributed System Manager does not show deployed libraries if they contain non-Latin characters. If a library with non-Latin characters (such as Japanese, Chinese, or Korean) is deployed, it will not show up in the NI Distributed System Manager tree view. Workaround: Rename the library using only the Latin alphabet and re-deploy the library.
| |||||
| 157246 Return | The Property Node "Bring to Front" doesn't work in Windows Vista Workaround: N/A
| |||||
| 128059 Return | Shared variable bindings in the same library are not updated properly when copying/renaming the library If you have shared variables in a library which are bound to I/O servers or other variables that are also in the same library, and you rename or save a copy of the library, the bindings still refer to the original library name. Workaround: Manually rebind the variables after copying or renaming the library.
| |||||
| 166253 Return | LabVIEW.app does not show up after LabVIEW 2009 Installation Workaround: This is only an issue for customers who installed the LabVIEW 2009 Beta for Mac. Delete /Library/Receipts/LabVIEW*9.0.pkg before running the LabVIEW 2009 installer for Mac OS.
| |||||
| 181687 Return | Web publishing tool fails without error The web publishing tool may fail to start the web server if the port is already reserved, yet not return an error. Workaround: Ensure that the port to be used by the web server is not in use.
| |||||

| |||||
| 163371 Return | "Save As:Copy" on a nested library breaks member VIs if use option to add copied library to owner library Old Description :"Save As:Copy" on a nested library breaks member VIs if use option to add copied library to owner libraryIf you have a nested library, a library that is owned by another library, and you use Save As:Copy, there is an option to add the duplicate library to the original owner library. If you use this option, the member VIs of the duplicate library are all broken because they are not correctly named as members of the owning library.This bug affects all types of libraries, .lvlib, .lvclass, .xctl and .lvsc. Workaround: Option 1: Do not use the "add to owning library" option and instead add the duplicate library to the owner manually after the copy. Option 2: After the copy operation, open and close one of the new VIs and then move the duplicate library out of the owner library. Browse to any missing VIs that pop up a browse dialog. Move the duplicate library back into the owner library.
| |||||
| 168005 Return | Dynamic Variable API Does Not Support I/O Servers that Use Ranges You cannot use the Variable classes, properties, and methods or the associated Shared Variable functions (Dynamic Variable API) to dynamically read and write PSP items published by an I/O Server that uses a Range item. For example, Modbus I/O Servers and Lookout Ranges are affected by this issue. Workaround: If you want to use the Dynamic Variable API to read or write one of these PSP items, you can create a network-published shared variable and bind it to the PSP item. Then you can use the Dynamic Variable API to read and write the bound shared variable.
| |||||
| 169840 Return | Large matrix operations that utilize the Intel MKL on Linux may crash LabVIEW When one or more matrix operations consumes most of the system resources, the Intel MKL library produces an unhandled exception that results in a LabVIEW application crashing.This Intel library is used to accelerate fundamental linear algebra operations performed under Linux operating systems. This issue has been reproduced outside the LabVIEW execution environment and a bug report has been submitted to Intel.Because the crash is tied to system resources, it can manifest itself in many ways. For example, we have reliably reproduced the problem by:1. Decomposing a large matrix into multiple large matrices.Specific example: Computing the singular value decomposition (SVD) of a 2500-by-2500 matrix on a system with 256M RAM.2. Simultaneously computing multiple matrix operations using relatively small matrices.Specific example: Computing 30 matrix expressions using 300 x 300 matrices on a system with 512 MB RAM. Workaround: If you have identified one or more matrix operations in your application that exhibit this behavior, you have multiple options to avoid crashing.1. Serialize the matrix operations so that they are not consuming resources in parallel.2. Replace affected matrix arithmetic functions using Basic Linear Algebra Subroutine (BLAS)functions found on the BLAS palette.3. Structure your application so that these operations are not competing with other functions for system resources.
| |||||
| 103315 Return | Creating a circular link between an Xcontrol and a LVClass can crash LabVIEW. The circular load leads to VIs that are permanently broken and no matter what you do the run arrow will not become fixed. Workaround: Do not create a circular link from your XControl to your class. In other words, write your class completely and then write your XControl using the class. Do not put the XControl or any property/invoke node for the XControl into member VIs of the class.
| |||||
| 95055 Return | Save for previous fails if file path is too long Save for previous copies the folder being saved to a temp location; if the resulting file paths exceed the limit defined by the OS, the function fails. Workaround: Copy the folder being saved to the root directory to reduce the file path length and Save for Previous from that location.
| |||||
| 198717 Return | Unflatten From XML fails for cluster and arrays that consist of variants Creating a cluster that contains a variant or building an array of variants, and then trying to flatten it to XML using the Flatten To XML VI and then unflattening it using the Unflatten From XML VI will throw error 1106 Workaround: N/A
| |||||
| 208364 Return | LabVIEW built installers created on a 32-bit machine will not install most drivers when run on a 64-bit machine If you build an installer using LabVIEW on a 32-bit machine that contains National Instruments drivers, the corresponding drivers will not be installed if the installer is run on a 64-bit machine. Drivers such as NI-DAQ, NI-Sync etc. are affected by this issue. Installation on 32-bit machines are not affected by this bug. Workaround: On the deployment 64-bit machine, download and install the missing drivers from the ni.com Drivers and Updates page
| |||||
| 213279 Return | Some nodes may crash or yield incorrect/inconsistent results when Inlined An Inline public methodVI calling a private-scope method VI, inlined into a non-class caller may give a runtime error when trying to call the private method from the inlined code in the non-class caller. Workaround: Do not try to Inline VIs with these nodes.
| |||||
| 208088 Return | Updating the Labels of a Cluster Written to a Chart Does Not Update the Cluster Used for Chart History Changing the Label of elements in a cluster written to the Waveform Chart does not update the label of the cluster when read from the Waveform Chart Data History Property. Workaround: Temporarily wire up a completely different data type to the Waveform chart indicator and then rewire the original cluster. The changes will now propagate to the Chart History.
| |||||
| 188911 Return | Control image alignment incorrect when "new report page" VI is used When using Append Control Image to Report.vi, the alignment of some images are ignored when New Report Page.vi is used between appended images. This problem only exists with Office 2007. Other versions - Office 2003 and Office 2010 do not exhibit this behavior. Workaround: Use a New Report Line.vi between appending the image and the New Page.vi
| |||||
| 227609 Return | Statically linking a LabVIEW built DLL in a C++ project results in error 998 if the DLL is not added to the Delay Loaded DLLs list Workaround: Go to the Project Property Pages, Configuration Properties»Linker»Input and add the name of your DLL to the Delay Loaded DLLs list.
| |||||
| 153731 Return | Unhandled Exception can occur if absolute path for system DLL used in CLFN If you use a specific path to a system DLL (C:\windows\system\user32.dll) and build your VI into an application it will create a copy of the DLL inside the application. This can cause an unhandled exception when running Workaround: LabVIEW searches in the system directory when looking for DLLs. If you are using a system DLL simply put the name in the in DLL Path box in the CLFN properties. In the example above you would simply put "user32.dll"
| |||||
| 185890 Return | Text on a VI can be mutated to appear as Unicode After building a project into an executable, various text for controls and indicators changes languages. It appears that the text was interpreted as Unicode.We have not been able to reproduce this in house to find a definite cause. Because of this we will leave this CAR open even though we have created code to recover from the corruption if it happens.Previously tracked as CAR 179683 Workaround: Upgrade the VI to LabVIEW 2011. In 2011 we put in code to only view text on VIs as unicode if the UseUnicode=True is in the LabVIEW .ini file. Previously this would only switch on the ability to change something to unicode.When the VI is upgraded to 2011 it should be saved and then saved for previous to return it to the original version.
| |||||
| 218083 Return | VIs with errors may show additional errors for code in disabled frames of Conditional Disable Structure If you have a VI that has errors in it, there may be additional errors shown. The errors will be in code that is inside of a disabled frame of the Conditional Disable Structure (in the "Default" or "Windows" frame when on RT). Workaround: Fix the other errors in the VI, and the additional errors should go away.
| |||||
| 227030 Return | Wait on Notification from Multiple function has unexpected behavior when ignoring previous input. Workaround:
| |||||
| 229641 Return | Hang can occur when deploying RT project that has not been check out of VSS When using VSS source code control for a real time project and trying to deploy code that has not been checked off the deployment window blocks a pop up from VSS saying that the code has not been checked out. The deployment status window is modal so it does not allow you to select to proceed in the VSS window. Workaround: In the LabVIEW project properties disable the prompts from source code control. Or you could make sure that the VIs are saved prior to deploying.
| |||||
| 232348 Return | Changes to a library item's access scope sometimes do not update broken callers. Changing a library item's access scope sometimes does not update callers which are broken only because they were attempting to access an item which was out of scope to them. Workaround: Force recompile (ctrl+click on the run arrow) any VI which incorrectly believes that access scope forbids access to it's dependency. Changing the access scope to another value, then back to the desired value while the VI is open will also fix the issue.
| |||||
| 235019 Return | OpenSSL fatal error when LabVIEW exits The OpenSSL fatal error possibly occurs when using Search features in LabVIEW for the first time after installation. Workaround: Launch LabVIEW and exit when Getting Started Window opens. The error now goes away in future launchings.

| |||||
| 196607 Return | DTbl Replace Subset VI behavior change between LabVIEW 8.6.1 and 2009 The start input indexes from the replacement data instead of the existing data Workaround: Set the index of data to replace from 0
| |||||
| 226840 Return | Formula VI does not execute pow(x,y) function Workaround: Use the formula node to use the pow(x,y) function. If you need to change this programmatically, use the Power of X function in G code.
| |||||
| 236377 Return | Dropping XControl from public library breaks XControl When adding an X control from a public library into the controls palette, it become broken when dropped down to the front panel from the controls palette. Workaround: Include a merge VI in the functions palette
| |||||
| 248914 Return | Changing the order of controls or deleting controls in a type def cluster can change references When you create a reference for a control in a type defined cluster LabVIEW uses the cluster order to determine what control the reference is referring to. Say you have a type defined cluster with elements A, B, C and D with cluster order 1,2,3 and 4 respectively. On the block diagram of a VI you have control references to each of the controls. If you open the type def and delete control C the block diagram of the VI will only contain 3 references. Moreover, the reference that used to be for control C will now reference control D. This is because the control is based on cluster order Workaround: N/A
| |||||
| 322914 Return | Formula VI does not execute pow(x,y) function Workaround: Use the formula node to use the pow(x,y) function. If you need to change this programmatically, use the Power of X function in G code.
| |||||
| 256141 Return | Windows 7 often shows "(Not Responding)" and will bring other windows to the front during expensive operations If Windows 7 if a window is unresponsive to user input (e.g. mouse clicks) for five seconds it will ghost the window and display "(Not Responding)".Some operations in LabVIEW run in the UI thread. This is to prevent different operations from happening in parallel (e.g. compiling, edit operations, saving, drawing, etc.). Because large block diagrams can take longer than five seconds to compile or run clean up on Windows can tag LabVIEW as Not Responding.In some cases the ghosted window can move behind the other open windows when it finishes it task. Workaround: Wait until the expensive task as finished before trying to interact with the window.
| |||||
| 248421 Return | Bitshift does not work correctly in Expression Nodes and Formula Nodes with a data type smaller than I32 Workaround: N/A
| |||||
| 250588 Return | Warning Generated in a Method or Property of an XControl Appears as an Error in the Top Level VI If you create a method or a property in an Xcontrol in which you have implemented code to generate a warning it is transformed into an error in the calling VI. Workaround: In the VI look for specific error and transform back to a warning
| |||||
| 255466 Return | Shared variable moved from a project directly to a tab control is not added to the active page. Workaround: After dragging the variable to the tab control. Reselect it and drag it slightly until the dotted lines appear around the tab control page and then drop it. The shadow is then removed because the variable has been added to the active page.
| |||||
| 236193 Return | Crash with invalid input (o or negative values) of "samples per channel" when misusing TDMS Set Channel Information There are some situations if you set the value of "samples per channel" of TDMS Set Channel Information as 0 or negative values (invalid values), which could cause a crash. Workaround: Avoid using 0 or negative values as "samples per channel".
| |||||
| 245148 Return | Class Properties dialog sometimes throws timeout error 123 when opening and must be restarted In LV 2010, there appears to be a timing race condition in the Class Properties dialog for LabVIEW classes. Every once in a while if you try to launch the dialog, the dialog will throw an error dialog reporting error 123 that the dialog has timed out while trying to launch. After you dismiss the dialog, you may see a secondary error dialog. Once you dismiss that, you can relaunch the Class Properties dialog and will generally succeed. There is no danger to your class and no corruption to you class file has occurred. It is solely a bug in trying to launch the dialog. Workaround: Hit Continue or OK button to dismiss all error dialogs that come up then retry opening the Class Properties dialog.
| |||||
| 251105 Return | S&V XControls built as Remote Panel crashes LabVIEW. Remote panels do not reliably support the Sound and Vibration XControls. Workaround: Use another mechanism for remote viewing.
| |||||
| 275961 Return | Silver style Thermometer frame doesn't resize correctly when control is resized. Workaround: N/A
| |||||
| 289842 Return | Get Variant Attribute VI returns wrong value if attribute not found The default value that's returned by the Get Variant Attribute VI is not blank when nothing is wired to the default value terminal. The Get Variant Attribute instead seems to return the last/previous value it returned as the default value. Workaround: Use the Found? output and logic to return a blank variant if necessary
| |||||
| 290105 Return | Text Labels in Silver Control are not in silver style Workaround: N/A
| |||||
| 238713 Return | 3D Picture Controls can display transparently or crash LabVIEW on certain graphics cards The 3D Picture Control is built on a OpenSceneGraph which uses OpenGL. Several reports of the 3D picture control crashing LabVIEW have been reported. In almost all cases it was an Intel integrated graphics card involved. This crash is caused by an incompatibility of the graphics hardware.Note: Many of the 3D Graphs use the 3D Picture Control Workaround: There have been several things that have worked for users:
| |||||
| 284936 Return | Breaking one Override VI in LVOOP shows all siblings as broken but does not explain why When using OOP in LabVIEW, breaking the connector pane of a child class Override VI will make all of its sibling override VI's appear broken even though they are not broken. Hitting run on the broken Run Arrow of any child class Override VI will list all of the child class VIs in the list of "Items with Errors", but none of them will have an error associated with it except for the broken ones. Workaround: Use the red X in the errors window to find the actual broken VI
| |||||
| 186808 Return | Shared Variable library on PC is undeployed if the a V in the same project is programmatically deployed to a Real-Time target When programmatically deploying a VI to a Real-Time target the Shared Variable library residing in the same project as the deployed VI will be undeployed. Workaround: Programmatically deploy the shared variable library on the PC after deploying the VI to the real-time controller.
| |||||
| 284289 Return | Source distributions with block diagrams removed prevents the use of static Shared Variable nodes. Source distributions that include static Shared Variable nodes with block diagrams removed will return the following error at run-time, "VI has a bad connection to or cannot find a subVI or external routine." Workaround: Use the Programmatic Shared Variable API or do not remove the block diagrams.
| |||||
| 257194 Return | Connector pane of a VI can change from LabVIEW 2009 to LabVIEW 2011 If you have a VI with no items in the connector pane and upgrade it straight form LabVIEW 2009 to LabVIEW 2011 then the connector pane may change Workaround: Open in LabVIEW 2010 first
| |||||
| 279373 Return | SMTP has been updated to use port 587; LabVIEW makes use of legacy port 25 The SMTP has been updated to use port 587 instead of port 25. LabVIEW still makes use of port 25 with its SMTP VIs. Workaround: Open any SMTP VI, and find the SMTP_CreateSession.vi. Open that VI, you will find a numeric constant on the block diagram that is set to 25.
| |||||
| 282737 Return | Applications with Chinese characters in the executable name will throw fatal error on English Windows 7 Workaround: Use a different name for the executable.
| |||||
| 294285 Return | Type Defined Shared Variable not found in Executable When a VI is made with the following conditions:1) Uses a Shared Variable attached to a type definition2) The type defined control (attached to the shared variable) is not in the main project directory (ie, it is in a different folder)3) The VI uses dynamic data (or waveform to dynamic data function)A created executable seems to not include the *.ctl file defining the shared variable type. This missing type definition causes the run time engine, when starting the executable, to search for and (if the control is not located in the searched directories) fail to find the *.ctl file. If the location of the *.ctl file is specified, the executable runs without issues. Workaround: Disconnect from Type Def during the build.
| |||||
| 320485 Return | User Events Created from Objects Cause Broken Packed Library VIs If you are using an object as a user event, it works fine while in the LabVIEW environment. However, when compiled into a packed library, the user event refnum has a broken wire. Workaround: N/A

| 351741 Return | Panes 'Top' pixel coordinates will vary when Windows 'Aero' is enabled/disabled If the Windows Vista/7 option to "Use visual styles on windows and buttons" is enabled, a VI property node for Front Panel Window:Panel Bounds will return a different 'Top' value. Workaround: If you are calculating the position of elements within your VI based on this value, check the deployed OS, and subtract an offset value.
| |||||
| 359662 Return | Some dotted scripting property calls can crash LabVIEW if earlier properties error If you access the property LinkedControl.ClassName on an object that does not have a linked control error 1308 will be thrown. If you access the property 3 times, LabVIEW will crash. Workaround: Separate into two calls; e.g. change a property of LinkedControl.ClassName into a call to LinkedControl, which emits a reference and, if successful, wire that to a second property node to get ClassName.
| |||||
| 356420 Return | Robotics Wizard cannot load a manifest file in a folder with a Chinese character in the name Robotics Wizard cannot load a manifest file in a folder with a Chinese character in the name Workaround: Move the manifest file to a new location
| |||||
| 244551 Return | Editing large strict type definitions can take a long time to update When large type definitions are updated, all instances in memory require an update. This update can take many minutes for very large type definitions. Workaround: Use smaller type definitions, or consider using LabVIEW classes to contain your type data.
| |||||
| 202192 Return | LabVIEW UDP broadcast is inconsistent across different OS's. If the UDP Open VI has 0.0.0.0 wired to the Net Address terminal, the behavior varies with OS. Windows XP and NI ETS will send on all interfaces, while Windows Vista, Windows 7, VxWorks, and Linux will send on the default interface. Workaround: N/a
| |||||
| 239719 Return | Property page doesn't update when Adapt to Source is coerced to off If you have a FXP constant with Adapt to Entered Data set and make any modifications to the display format, the resulting constant will not be set to adapt.

| 559606 Return | In rare cases, leaving the Index input of Index Array function retrieves correct data but can cause other math functions to return incorrect results. Workaround: Wire the index terminal of the Index Array function.
| |||||
| 563825 Return | In certain rare cases, the Not A Number/Path/Refnum? function can cause LabVIEW 64-bit to crash; LabVIEW 32-bit is unaffected. Note: A recompile of the VI using the function is required to apply the fix. Workaround: This has been fixed in the LabVIEW 2014 SP1 f5 Patch
| |||||
| 574488 Return | Upgrading to Mac OS X 10.11 (El Capitan) prevents Source Control in LabVIEW from finding Perforce Mac OS X El Capitan no longer allows third party applications to be installed in /usr/sbin or /usr/bin. This is the default directory where many third-party applications have been stored in the past including Perforce. OS X El Capitan actually strips out any files from this directory that were user installed. Therefore, if you have Peforce installed in /usr/sbin, are running OS X 10.10, and upgrade to OS X 10.11, it strips out the Perforce files. Workaround: Manually copy Peforce back to /usr/bin (need admin rights).
| |||||
| 561615 Return | In specific cases, building a LabVIEW executable with shared variables causes Error 1003 during the build. The user will get an error saying, "VI containing Shared Variable node needs to be loaded in a project" on the Build Errors Dialog. Workaround: Save the VIs in the project that contain shared variables.
