TestStand 2021 shows "No Supported languages installed" error followed by "Unable to open resource file" error and crashes

[GirishVrishab]

I had created a LabView VI and Teststand Sequence which were working together as per my requirement. But for some reason, I had to uninstall and reinstall multiple Labview and Teststand versions and finally settled with Labview 2020 and Teststand 2021. Now, the challenge is when i run the previously created VI independently, it works fine. But when i call the same VI from Teststand, i am getting an error saying "No Supported Languages installed" followed by another error saying "Unable to open resource files" and then Teststand crashes. Any suggestions what would have gone wrong? I am using Windows 10 - and LabView and TestStand are of 64 bit versions

Hi GirishVrishab,

Can you provide some more context on why you "had to uninstall and reinstall multiple LabVIEW and TestStand versions"?

I would start by going into NI Package Manager and repairing LabVIEW and TestStand, starting with TestStand since LabVIEW appears to be working fine on its own.

Hi, Repairing all TestStand components through NI Manager fixed the issue. Thanks a lot for your inputs.
