| 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
| |||||
| 312071 Return | Error 7 when using Report Generation Toolkit VIs in a DLL By default Report Generation Toolkit VI's are compiled into the DLL, but can't be executed from within the DLL. Workaround: The DLL will run correctly if you include the Report Generation toolkit lvclass dependencies in a separate support directory and specify that they are always included in a data directory.
| |||||
| 382455 Return | Microsoft Excel Template named cell range font size is overwritten When appending cell data to named cell ranges from Microsoft Excel Templates, font size is always size 10pt. Workaround: Use Excel Set Cell Font.vi to manually set the desired font for each named range.
| |||||
| 391394 Return | Dates are Reversed by Excel Easy Table.vi on Non-US Languages The month and day are reversed when exporting data to Excel for languages other than US-English. For example 03/02/2013 (3rd of February 2013) in LabVIEW is exported as 02/03/2013 and considered as 2nd of March 2013 by Excel. Workaround: N/A
| |||||
| 472835 Return | The Save Report to File.vi requires the "report file path" terminal to be wired, but is not set as a required input The VI will return Error -41003 when running the VI if the path is not wired or empty. This requirement is enforced in the VI itself, so it will not break the run arrow. Workaround: Wire the file path of the report to the VI.
| |||||
| 631802 Return | Exporting typedef array of numerics to Excel may crash LabVIEW When using the right-click menu option to export a non-empty, typedef numeric array's data to Excel, LabVIEW will crash. Workaround: N/A
| |||||
| 637867 Return | LabVIEW 64-bit on Mac OS X ignores the orientation specified in the Layout Options input of the Easy Print VI Panel or Documentation VI. N/A Workaround: Use LabVIEW 32-bit for Mac OS X or configure the printing device instead.
| |||||
| 642790 Return | Executables built on a machine with version 1609 of Office 365 and run on earlier versions crash when trying to save Excel sheets In version 1609 of Office 365, the ActiveX API for interacting with Excel was changed. The SaveAs method now has a new parameter called WorkIdentity. If you run an executable that has this new parameter on the invoke node on a version before 1609, the executable will crash when attempting to save the Excel file. If the executable is built in a version prior to 1609, it will run on later versions with no issues. Workaround: Ensure both the build and deployment machines have the same version of Office installed, use a version earlier than 1609 to build the executable, or build the Excel_Save_Workbook VI into a Packed Project Library.
| |||||
| Toolkit - Unit Test Framework | ||||||
| 120941 Return | Code Coverage analysis is not supported on LabVIEW Real-Time The Unit Test Framework Toolkit cannot measure code coverage on real-time (RT) targets. The result will always be zero. Workaround: N/A
| |||||

| |||||
| 171553 Return | File load conflict after dragging multiple LV Classes to another context You will get loading conflict for lvtest files if you open a project which has multiple LV Classes and those classes have lvtest files of the same name. Loading any VI will also be very slow if you have this loading conflict in your project. Workaround: Rename the lvtest files to different names. Or remove those lvtest files from the project and re-add them.
| |||||
| 420795 Return | When creating a custom LV project template with the Unit Test Framework .lvtest file, the new project will overwrite the original template when saving instead of creating a new instance with new files. Workaround: N/A
| |||||
| 466818 Return | Error 1527 will occur when running the example "Programmatically Run Tests from Projects.vi" referencing the example project "LV Class.lvproj." Workaround: 1. Open LV Class.lvproj 2. Open by double clicking in Windows Explorer "Programmatically Run Tests from Projects.vi" (Now the VI will be in the LV Class.lvproj LabVIEW instance) 3. Modify "Programmatically Run Tests from Projects.vi" to run LV Class.lvproj 4. Run the VI
| |||||
| 475037 Return | Enabling loop iteration parallelism in For Loops results lower code coverage than expected A For Loop configured for parallelism is incorrectly counted as an uncovered diagram when calculating code coverage Workaround: Turn off parallelism or set the for loop to "Allow debugging" for the code coverage test
| |||||
| 471993 Return | Cannot create Unit Test for VI with control connected to the terminal and inside a tab control This result in an error: LabVIEW: Type Mismatch: Object cannot be cast into the specified type.
