(open) [HOU-4815] Houdini 20.5.584 is having issues with V-Ray Adv 7.00.10 on Win 11

[gleavitt]

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):

Dear gleavitt, hello.

All screenshots show that V-Ray is not properly installed.
The reason is the Houdini 20.5.584 was released four days ago and the latest supported version in our nightly builds is 20.5.550.
If you run the installer and click on Advanced you will see the directories where the installation will be made and a list with supported versions.

Example from latest nightly:


Best regards,
