I just installed Acrobat DC via Creative Cloud on Windows 10. On launching Acrobat DC, it automatically pops up some sort of tutorial/help window, which then closes and reopens over and over again, preventing me from using the application. I can't access any file menu options in Acrobat because of this. I tried uninstalling and reinstalling both Creative Cloud and Acrobat DC, but it did not fix the issue. Any ideas on what might be going on?
