MacOS 10.12.6 can't start Premiere Pro 12.1, Photoshop 19.1.3 or After Effects 15.1 anymore

@mattchristensen I had a conversation with the telephone-Support. Here is the Ticket-Number if it is any help for solving the Problem: ADB-41039235-M4M3 

It startet when I wanted to fix a problem with the Synchronising of the Adobe-fonts. I followed the Instructions on link in the creative cloud-App to solve the Synchronisation-problem.

Sorry, I forgot to translate: 

Unfortunately, none of the installed browsers can open the website. I am logged in to the Creative Cloud app on the computer. There I also see the programs, but it also starts here the application manager if I want to start the program.

Leider kann keiner der installierten Browser die Ebseite öffen. Ich bin aber auf dem Rechner in der Creative-Cloud app angemeldet. Dort sehe ich auch die Programme, es startet aber auch hier der Application-Manager wenn ich das Programm starten will.

@uwe_9581 I'm sorry about that. One thing to try is to use your default browser and go to creativecloud.adobe.com and log in there. Once you're in, you should see an interface that looks similar to the Creative Cloud Desktop application.

Now that your browser is logged in, try the steps you did before – any chance that works?
