Reactivation of Archived machines in Device licensing failed

Hello, I am from Germany.

We have a 100license for education and I deactivated one license on a backup Mac from admin console.

Now we need the backup Mac and I tried to reactivate the CC.

I installed the actual cc-package, but applications don´t start.

I followed the instructions on the "Reactivation of Archived machines in Device licensing failed" Site, but I didn't´get the the command’s return code as zero, my code is "28"

So, what now? I am desperately and don't know what to do ....

I Hope you can help.

Best regards

Christian
