• 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

🐞 Describe the bug

Hi..
with Pyrevit 6.4.26100 and Revit 2025/2026 I receive an erron on startup
This is the screenshot
If I uninstall pyrevit, revit start correctly

By the look of it, it seemed to be an install that got wrong (probably because the previous install was not uninstalled beforehand)
Try removing the pyrevit-config.ini from the %appdata%/pyrevit (or pyrevit-master) folder

I tryied to uninstall all and delete folders, but i receive the error yet

I'm having the same problem, I don't know how to fix it. I already uninstalled it and deleted all the files.

Can you try to install the regular exe (not the admin one)? @xkevix

[hantrax]

Thanks
I tried to install the EXE wiyhout admin ..but nothing to do
I receive the error on 2025 and 2026

I believe this issue is associated with Developer and/or Tutorial Extensions. Installing without both seems to fix the issue; installing with just Developer causes the same thing to happen.

Hi Andrea
I will try to install it without dev

Thanks

This fixed it for me. I copied the error into Claude and followed these instructions:

The pyRevitDevHooks.extension is a developer/debug extension that ships with pyRevit-Master. It registers callbacks on Revit events (including progress-changed, which fires very rapidly during model load and many other operations). Each fire tries to append to C:\Users\jsnyd\desktop\hooks.log, that path doesn't exist, the write throws, and pyRevit pops an error dialog. Because progress events fire continuously, you get the runaway cascade — each unhandled dialog leaks memory, and 60% RAM is just thousands of stacked error windows.

The path almost certainly fails because your Desktop is redirected to OneDrive (C:\Users\jsnyd\OneDrive\Desktop), so the literal C:\Users\jsnyd\Desktop folder no longer exists on disk. The hooks_logger.py has the path hardcoded or pulled from a config that's now stale.

Solution: Fix the log path in code. Open C:\Users\jsnyd\AppData\Roaming\pyRevit-Master\extensions\pyRevitDevHooks.extension\lib\hooks_logger.py and look near line 17 (_write_record) and line 46 (log_hook). The hardcoded path will be there. Repoint it to something stable like %APPDATA%\pyRevit-Master\hooks.log or wrap the file open in a try/except so failures don't propagate as dialogs. Something like:

pythonimport os
LOG_PATH = os.path.join(os.environ.get('APPDATA', ''), 'pyRevit-Master', 'hooks.log')

def _write_record(record):
    try:
        with open(LOG_PATH, 'a') as f:
            f.write(record + '\n')
    except (IOError, OSError):
        pass  # silently drop if path unavailable

Cleanup note for multi-Revit setups:

pyRevit-Master is the dev/nightly channel and is more prone to issues like this. If you don't need the bleeding edge, switch to the stable pyRevit release — it doesn't ship the DevHooks extension enabled by default, and you'll avoid this class of problem across all your Revit versions in one shot. Both can coexist, but pick one as primary to keep your extensions folder clean.
Disabling the extension is the recommended path unless you're actively developing hooks.To run code, enable code execution and file creation in Settings > Capabilities.

I installed without dev and now work fine
Thanks
