Opening program defaults license to Cloud zoo; should be Standalone. I change to Standalone, If I close and reopen Rhino retains the standalone info, but it asks for re-registration and validation, I let it validate and Rhino opens. Closing, reopening repeats the re-registration and validation process. License splash:
@Fred_C looking at your licenses, it appears that yesterday you added your license to the Cloud Zoo. You won’t be able to validate your license on your computer until you remove the license from the Cloud Zoo. To do that, visit https://www.rhino3d.com/licenses and remove the license from your personal team.
