pyRevit for Revit 2025 hasn’t been released yet. I know the all volunteer team is working on it :slight_smile:

Pre-release is approaching 99% ready, want to try pyRevit in Revit 2025…

try the WIP Installers (Github account required)

Thank you for the great pyRevit, I did a lot of Revit add-ins using pyRevit, it’s a game changer.
I’ve tested the WIP release of pyRevit for Revit 2025, it works fine till now for 2025 but the previous versions aren’t working showing [Error loading pyRevit], below is the error

try with this installer in the meantime

Note that C# script won’t work in this version

it is still a WIP and we are working hard at it to make it fully functional.

Thank you very much, this build works fine

Just to confirm.
I am running Merge pull request #2357 as suggested.
It seems to work fine on Revits 2023, 2024, 2025.

I have install pyRevit_4.8.16. It does not work on Revit 2025. I got this error.

indeed, 4…8.16 is not compatible, use the wip installers to try it out (uninstall first)
download from pyrevitlabs website

And for good mesure:

Hello,
and Welcome

Hello,

First of all, I would like to apologize for my previous message and any confusion caused. Thank you so much for the wonderful PyRevit! I really appreciate the hard work that goes into this tool.

After following your advice and using the WIP installers, I am happy to report that PyRevit works perfectly on Revit 2025 for me.

Thank you once again for this magnificent tool and all the continuous improvements!
