🐞 Describe the bug

pyRevit Loader runtime error, fails to launch pyRevit.

Unistalled and reinstalled, unistalled revit and reinstalled, no solution, same error.

The issue was when I tried installing pyRevit on Revit 2024, was always working fine on previous Revit versions.

Please help. Thanks in advance.

I already followed the installation troubleshooting guide thoroughly

Have you really followed it?

[SpaceArchitecture]

Same problem with me, it seems the installer for the latest version doesn't like Revit 2024....
Too bad

[sanzoghenzo]

This is a known issue, and possible solutions are shown in the installation troubleshooting guide.

Until we have a confirmation that that guide has in fact being followed, and more info about the error is reported, we can't guess and provide any more info.

[SpaceArchitecture]

It's a known issue ? Is somebody working on a fix ? It seems pretty widespread.

[sanzoghenzo]

TL:DR: Yes; in our free, unpaid time; yes we know.

Long version:

• as I wrote earlier Yes, it is a known problem and many of the closed issues are a variation on this theme.
• the resolution of this problem is blocked by the ongoing changes related to supporting the new revit versions, but we have little to no time/resources to finish that (@dosymep did almost all the hard work, I don't have access to revit 2025, nobody else is trying to help)
• we know that it is widespread since we have to reply to each of the issues with the same answer 😉 the troubleshooting guide provides a workaround, but it seems that nobody reads it. The issues should be used to report problems only if the provided workarounds are not effective.

If it helps, the WIP build I installed last week is working fine in Revit 2024, although I have implemented the revit application fixed we discussed. Not sure if that helps identify the potential changes that cause the issues in that specific build?

I second @sanzoghenzo's call for patience and understanding. This is open source software that most are getting 100% free - there will be strings attached to this an it should be expected in using pyRevit that it takes as long as it takes. We greatly appreciate the hard work you're all putting into this when time allows.
