Answer:
Our authorization has a service entry. This entry describes whether a customer has purchased our software with a valid service contract (Basic, Pro) or without a service contract.For users who have a service contract, the end date related to the service contract concluded with us is stored in the entry. This form of authorization then accepts all assigned versions with a creation date before this date.
If the user has no service contract, only the version number (for example, 5.19 [major release number].[minor version number]) that is current as of the software purchase date is stored. In this case, the authorization only accepts the assigned versions with the same major and minor version numbers.
