deinstallation nach anweisung dauert wie lange?

Hi @Hedemaria30962470mcdk 

Sorry to hear about the trouble caused.

If you are still experiencing the same issue and the screen is stuck while uninstalling the app, then we suggest you reboot your system. 

After rebooting, look for the application to see if it's uninstalled or still there. If uninstallation is not done, then repeat the process after rebooting:

Run this cleaner tool to remove the existing installer and application’s file traces:

Download the Acrobat installer from here:
