@edpeca - Thanks for elevating this from email so that others can benefit from the recorded exchange.

First, can you confirm that you are on the WEIS develop branch? A git status command should tell you. Assuming that isn't the issue, can you also confirm that you don't have FileExplorer or other programs somehow blocking the access to the working folder where TurbSim is trying to run?

[edpeca]

Yes, I am currently using develop branch. I believe it might be due to Windows Secutiry blocking the access to OpenFast

[edpeca]

[gbarter]

That was going to be my next question. If you just type openfast -h and turbsim -h at the command line, does that work? Sounds like that is blocked?

[edpeca]

openfast -h works, but turbsim -h prompts "Access denied" and it is blocked by Windows Secutiry. I have raised a ticket in our IT management system

[gbarter]

Sounds good. Please let us know if the Windows Security fix resolves the issue.
