I recently purchased a upgrade version from Rhino 4.0 to Rhino 5.0, and have also V-Ray 1.5 for Rhino 4.0 and 5.0.
I run windows 8 64 bit OS (x64). Which version of Rhino should I install the v-ray the 32 bit or 64 bit ? Heard V-Ray runs only on 32 bit and I'm still having problems to complete the V-Ray installation.
When I start the render there is always a message "could not obtain a license" (PrtScn attached). Have everything installed, dongle attached, but still the message appears.
Hi Antonio- the license part you'll have to sort out with ChaosGroup (http://www.chaosgroup.com/forums/vbulletin/) They also say, about 32/64:
"* V-Ray for Rhino runs as a 32-bit application on Windows x64 and will also run as a 64-bit application with the 64-bit version of Rhino 5.
* V-Ray 1.5 for Rhino builds support Rhino 4 and Rhino 5."
Will sort it out with Chaosgroup.
I assume that you already had V-Ray 1.5 working in Rhino 4? (dongle correctly programmed, license server working, etc...)
For Rhino 5/64 bit you need to log back into ChaosGroup's download section and download the version for Rhino 5 64 bit. There is also one for Rhino 5/32 as well as a third for Rhino 4. Then, when installing, make sure it gets installed to the correct directory (check during the installation and again afterward). If you have a Rhino 5 Beta folder left over, it occasionally decides to install there, and that doesn't work.
Lastly, after the install, verify if the plug in is loaded in Options, and also that the license server is running. When in doubt, stop the license server from Windows Services and re-start it from Start>All Programs>Chaos Group>V-Ray...>Licensing>Start V-Ray license service.
If all that fails, you probably need to contact Chaos support directly.
Will try to reinstall.
Did you manage to sort it out ?
