🐞 Describe the bug

I installed the latest version of PyRevit with the aim on using it on Revit 22. After I installed it and open Revit I get a popup with a error stack.

⌨ Error/Debug Message

Hi @Pietieklipkop, Try these steps:

1. Uninstall pyRevit

2. Delete C:\ProgramData and %AppData%\ pyRevit and pyrevit-master folders

3. Move all Revit addins to a temporary location. Usual addins locations include:

   • %AppData%\Autodesk\Revit\Addins
   • %AppData%\Autodesk\ApplicationPlugins
   • %ProgramData%\Autodesk\Revit\Addins
   • %ProgramData%\Autodesk\ApplicationPlugins

4. [Reboot computer]

5. Reinstall pyRevit

6. Started each version of Revit confirming pyRevit successfully compiled at startup.

7. Move all Revit addins that were moved in step 3 back to their original location.
   You may want to add them one at a time and start a revit session everytime to figure out which ones are causing the issue.
