Instrument Studio Fails to start

[SMD123]

Hello there,

I have been trying to work with Instrument Studio, but everytime I try to open it, it doesn't. IT shows all the necessary files being prepared but does not open. I have viewed the problem  that was in the forum but couldn't find a way to apply it to my own system.

I have tried Repairing it, reinstalling it and also tried opening it as admin but did not open. Could you suggest me on what i should do?

It seems like we still need to collection some information to help us understand next steps.

The description of the behavior sounds like it might be crashing during launch. Perhaps the app left some error reports? Check this folder

C:\Users\__YOU__\AppData\Local\National Instruments\InstrumentStudio MM.m\ErrorReports

• __YOU__ is the user trying to launch InstrumentStudio
• MM.m is the version of InstrumentStudio being launched

Would you share a link to what you found?

Does your company happen to use an http proxy? If so, it might be blocking http2 traffic. Try setting the following environment variable and see if it resolves the issue.

‘NO_PROXY=localhost,127.0.0.1’

Thank you for the help. I tried it and it worked. There was a proxy server
