Error Launching Vray on revit 2020 startup

[kevin_caillaud]

Since the last update, I can no longer run the VRAY module when starting REVIT.

Here is the error log


Thanks

Hello Kevin,

It looks like a .dll file is missing from your V-Ray installation.
Can you try to uninstall V-Ray manually, then reinstall it.
If the issue persists, we'll also need to know if you're using any specific Revit addins.

Best,
Ana

hello Anna,

I verified, the dll is already in the folder of Vray location
I have already uninstall V-Ray manually, ans reinstall it. the issue still persit.
The only addin of revit,i have, is PyRevit.

Kevin,

Can you send us your exact V-Ray for Revit version as well as your exact version of Windows. It would be best if you simply screenshot both "About" windows. In addition, the version of PyRevit too (just in case).

Best,
Ana

Hi,

Please try the recommendation in this post: https://answers.microsoft.com/en-us/...d-ae0e197782e5

It looks like the issue may be caused by corrupted system DLL. Please advise if this has solved the problem for you.
