Thank you for the response Rob. Based on the Fluent 2022 R2 release notes my gpu should be supported - 

"Fluent supports NVIDIA's CUDA-enabled workstation, data center and server cards." 

Also, I am trying this on campus, so I am connected to the license server for sure. I can start and run Fluent in regular parallel CPU mode without any trouble.

Any other ideas on things to try?
