we are using Rhino 7 with Zoo license (30-user license, Educational). If we install update (new SR), the installer deletes lic file from c:\ProgramData\McNeel\Rhinoceros\6.0\License Manager\Licenses, so we need to specify the license on the first run of newly installed SR of Rhino 7.
Even if we specify the Zoo server in advanced settings of the installer.
Interestingly enough, it deletes only lic file of Rhino 7 and lic file of Rhino 6 keeps intact.
And Rhino 6 is not doing it.
We use classic Zoo server, not Cloud Zoo.
