1) Right click on Finder icon and select "Go-To" Folder option.
2) You will get a text box, type-in below command and then hit 'Return' key.( " Do not miss ~ symbol " )
It will open User Library folder.
3)Then navigate to Application Support>Adobe>OOBE. Open OOBE folder and trash Opm.db file.
Once you had trashed Opm.db file , re-launch Adobe Creative Cloud app and check.
