How to Set the Configuration Options
LabWindows/CVI development environment configuration options are under the following key, where [version] is the version of the LabWindows/CVI development environment:
HKEY_LOCAL_MACHINE\SOFTWARE\National Instruments\CVI\[version]
![]() |
Note Versions of LabWindows/CVI that follow year-based versioning continue to use major.minor versioning in registry keys. Refer to the LabWindows/CVI Year-Based and Major.Minor.Tiny Version Equivalents topic for the current major.minor version equivalent. |
Use this key to set the configuration options for the LabWindows/CVI development environment.
A configuration string value is associated with each option, as shown in the following figure.

You do not have to include an unused configuration string in the Registry.
You must specify an absolute pathname, including a drive letter, for configuration strings that take a directory name.
Runtime Configuration Options
The LabWindows/CVI Runtime configuration options are under the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\National Instruments\CVI Run-Time Engine\cvirte
![]() |
Note You must manually create the Registry key for a LabWindows/CVI Side-by-Side Runtime. |
Your programs, when you run them from the environment or as stand-alone applications, use the Runtime configuration options.
