This is still an issue with Houdini 20.5.584 using V-Ray 7.00.10. I have read other threads and there has not been a valid solution posted.
I have followed different suggestions from using the installer to using the zip file and pointing the json to the correct install folder for V-Ray for Houdini.
When Houdini starts up, I get errors. When I try to open V-Ray settings, I get an error message and when I go to the about V-Ray is says that python 3.10 is not installed. Well, I have python 3.11. I had 3.10 until I started having these issues. Please see the images for the messages I am getting. All of the files are where they are supposed to be.
Here is the traceback I get when I try to use a V-Ray tool:
Traceback (most recent call last):
