Rhino 6 error 200

I installed rhino, but after opening the program, error 200 appears (license manager initialization failed with error - 200. Rhino will not run)

  1. going to Control Panels didn’t help-> Programs and Features -> Selecting Rhino 6, right clicking and selecting Change, then hitting repair
  2. I have a problem with windows update not being installed correctly, especially .NET Framework 4.8
    Could you help me.
    Thank you

Hello - can you download and install 4.8 directly, or have you tried that?
