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

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: MSVCP140.dll Error - Microsoft Q&A

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