Univention Corporate Server, I can't activate it

Good afternoon. After installing Univention Corporate Server, I can’t activate it. I attach the ugs.license file. There is no result, why??. There is an endless Importing license data… Help me solve the problem

Hello @Dima,

what installation source did you use for UCS? ISO image, UCS virtual appliance or some app appliance?

For app appliances FAQ: App appliance activation errors could probably help.

Best regards,
