Everytime I go on any app I get a constant window popping up and disappearing so can't use anything, if I try close the pop up the whole program shuts, does anyone know how to fix this? On iMac
Thank you for posting your query here and sorry to hear about the trouble you are facing.
Please Open Windows Task Manager (for Windows computer ) or Mac Activity Monitor (for a Mac) and close all Adobe processes like Creative Cloud, CLibrary, CCXProcess, Adobe Update Service, Adobe Genuine Software Service, Adobe Acrobat Update Service, AcroTray etc.
Also please try a system restart and retry, it should work.
