I really enjoy errors in software that occur randomly for no reason. 🙂 One that recently occurred was an installed Adobe application (InDesign) that suddenly failed to start. Reinstalling the software didn’t help. Starting the application would run Adobe Creative Cloud instead where it tried to endlessly validate a software license.
This was fixed by deleting 4 folders:

  • C:\ProgramData\Adobe\SLstore
  • C:\Program Files (x86)\Common Files\Adobe\Adobe PCD
  • C:\Program Files (x86)\Common Files\Adobe\caps
  • C:\Users\[User Name]\AppData\Local\Adobe\OOBE

Once deleted, InDesign was able to run again after I logged into Adobe with my credentials.
