Rhino 7 released without support for running interactively on Windows Server. Since then, we’ve learned that tons of our Rhino 6 customers are successfully running on a variety of VDI platforms, and want to run Rhino 7 there, too.
We plan to release support for running Rhino interactively on Windows Server / Virtual Desktop in Rhino 7.4 (Due to be released March 10, 2021).
Neither Microsoft, nor any of the VDI providers, have a consistent way of indicating to applications that the application is running in a virtual desktop environment - so we have to work to support each vendor specifically.
If you are trying to get Rhino 7 working on Windows Server, please download the Rhino 7 Release Candidate and let us know if it works.
