We are receiving the following error when trying to install any of the PyRevit extensions. We have tried uninstalling and reinstalling the latest version.

I cannot reproduce,
Which extension are you trying to install? One in particular? or none are working?
None of them are working in either Revit 2024 or Revit 2025. I found a possible solution in another post (below) waiting on IT confirming we can try. Thanks Lynsay
I doubt it will work, this is old news. but feel free to try.
What does pyrevit env command line output?
You’re right it didn’t work.
Command Line Output as follows

can you show what is there: C:\Users[redacted]\AppData\Roaming\pyRevit\Extensions?
there should be a extensions.json file minimally.
other avenue, try to uninstall pyrevit and install the latest WIP using the pyrevit…_signed.exe file.
These are the extensions I installed some time ago, I have been trying to install pyArchitect and that’s when I get the error that it won’t install and it doesn’t create a folder for that extension or a .json file
Also where can I access the latest WIP exe file?
one level up you should have a pyrevit-config.ini file, send me the content in DM please
have you tried uninstalling and then installing this one then?
Issue has now been solved - IT security was blocking the url for extensions. Thanks for helping. Lynsay
