Working with pyrevit 5.3.1 with several Revit versions did not have this issue.
I’ve installed pyRevit 6 after closing Revit and removing the old pyRevit version.
I’m working with Revit 2024.3

How to solve this problem?
Thanks in advance

Here’s my log-file.

I am getting the same message, but only in Revit 2024.

yes,
thanks,
this has been picked up in the WIP.
I would need to double check, but you can too, by installing the latest wip installer (remember to unsintall the previous version)

@Jean-Marc

Thanks for the tip.

I’ve closed Revit, uninstalled pyRevit and removed folder %APPDATA%/pyRevit
Next I installed pyRevit 6.1.0 (file "pyRevit_6.1.0.26047_signed.exe)

After starting Revit this issue is still not resolved in pyRevit 6.1.0
Revit doesnt’recognize installed Revit-version → scripts of all Revit-versions are visible :frowning:
(Working with pyRevit 5.3.1 with several Revit versions did not have this issue.)
Any suggestions how to solve this problem?

(tested in Revit 2024/2025/2026)

I use bundle.yaml, I think this is broken in pyRevit 6.x

# minimium supported Revit version
min_revit_version: 2025

# maximum supported Revit version
max_revit_version: 2024
