unable to acquire v-ray for rhino gui license

[Camaieu]

Hi, I saw this topic but the answers found could not solve my problem, maybe someone can help me?
I just Installed the Windows 11 and Rhino 7 and V-Ray for Rhino 7 but when I start Windows the two windows are opening and they stay black they don´t go away anymore and when starting Rhino and V-ray the message appears "unable to acquire v-ray for rhino gui license, I have also installed the licence server a part as mentioned in one of the posts and when I check Localhost the licence is ok and green, I would appreciate if you can help, Thanks in advance

Regarding the licensing error, make sure you are installing the correct version of V-Ray for your licenses. If you have V-Ray 3 licenses V-Ray 3.x.x, for V-Ray NEXT look for V-Ray NEXT builds and so on. Licenses are backwards compatible but you can't use V-Ray 6 with older licenses for example with 5 or NEXT.
