[Bug]: PyRevit error only in Revit 2024

[Scott55555]

✈ Pre-Flight checks

• I don't have SentinelOne antivirus installed (see above for the solution)
• I have searched in the issues (open and closed) but couldn't find a similar issue
• I have searched in the pyRevit Forum for similar issues
• I already followed the installation troubleshooting guide thoroughly
• I am using the latest pyRevit Version

🐞 Describe the bug

Hi all

Had issues with pyRevit_4.8.16.24121_signed [tried the admin one] on Windows 11 with Revit 2023 and 2024. Everything is patched and up to date.

Followed the below guide and got it working in Revit 2023 but Revit 2024 still throws the issue 'Error dynamically compiling pyRevit runtime'

Fix followed which got it working in 2023 [but not 2024]:

---

Uninstall pyRevit
Delete ‘C:\ProgramData’ and ‘%AppData%\ pyRevit’ folders
Move all Revit addins to a temporary location. Usual addins locations include:

%AppData%\Autodesk\Revit\Addins<year>
%AppData%\Autodesk\ApplicationPlugins
%ProgramData%\Autodesk\Revit\Addins<year>
%ProgramData%\Autodesk\ApplicationPlugins\

Reboot computer
Reinstall pyRevit
Started each version of Revit confirming pyRevit successfully compiled at startup.
Moved all Revit addins that were moved in step 3 back to their original location.

---

Many thanks.
