Even though I have a valid license for Creatve Cloud and Acrobat DC, I get the following when I try to use it an the next message when I try to sign into my account in Acrobat. Eventually I can sign in, but the next time I go to use it or if I restart my computer, it happens again. Please help!
Hope you are doing well and sorry for the trouble. As described you are getting the error message 'Adobe Acrobat license has either expired or not been activated' followed by another error 'initializing registration'
Also, for the 'initializing registration' error please try the following steps (Win OS)
1) Close all adobe related processes in task manager (Core sync, services for adobe desktop app, adobe desktop service, Adobe IPC broker, AAM updater)
2) Navigate to following locations and assign the current user full permissions to adobe folders. (Right click on adobe folder select properties then click security tab , click edit and select current user you are signed in with , select full control , click apply and then ok)
C://program data (enable view hidden files to see this folder)
C://program files 86x/common files
C://program files 86x/
C://program files/common files
C: //program files/
3) rename SLstore to Slstore.old at following location c://program data/Adobe/
