Additional Information
You can refer to
LabVIEW readme file available at your specific LabVIEW download page. If LabVIEW is already installed, and its version is not higher than 2020 SP1, you can find it under
C:\Program Files (x86)\National Instruments\LabVIEW [version number]\readme to check which .NET Framework is required. This is typically indicated under
System Requirements section.
If you need to install a different version of the .NET Framework other than what is on your machine, download different versions from
Microsoft's .NET Framework download page.
