I actually had the trouble - as many others - that I invited a member to the Creative Cloud Team and after he connects all CC-Stuff is only available in trials versions.
So after a lot of reading and trying I have the following solution which is important for the most people sitting in an office:
Try this URL in a webbrowser: https://lm.licenses.adobe.com/
If you get: "Congratulations! You have successfully connected to Adobe License Management Server" - everything is fine and it must work.
If you get an error page or nothing - you have a problem. But which one?
The cloud application trys to connect to the https-Port and in most of the companies the firewall is configured not to allow access via https. Thats the point a lot of trouble comes from.
Hopefully this helps.
Unfortunately ,the activation is required.You must allow Adobe activation server on your firewall or connect to another internet connection to activate .
Here are the most important links to allow :
- Ports : 443 et 80 (TCP)
- Applications : "Adobe Application Manager" et "PDApp"
- URLs :
