Solution 1: Remove the opm.db file, restart your computer, and relaunch the Creative Cloud app
Quit the Creative Cloud Desktop application from the gear icon in the upper-right corner.
Browse to the following location based on your operating system to locate and delete the opm.db file.
Mac OS: /Users/<user folder>/Library/Application Support/Adobe/OOBE
Windows: C:\Users\<user folder>\AppData\Local\Adobe\OOBE
Restart the computer and launch the Creative Cloud Desktop application again.
Solution 2: Delete the contents of the OOBE folder and relaunch the Creative Cloud app
Quit the Creative Cloud app from the gear icon in the upper-right corner.
Browse to the following location based on your operating system
Mac OS: /Users/<user folder>/Library/Application Support/Adobe/OOBE
Windows: C:\Users\<user folder>\AppData\Local\Adobe\OOBE
Delete the entire contents of the OOBE folder.
Note: This folder is the one containing the opm.db file from solution 1.
Restart the computer and launch the Creative Cloud Desktop application again.
Note: The app can take slightly longer than usual to load with this solution, as content in the OOBE folder is rebuilt after launch.
