1. Quit Application Manager from its menu-bar icon at the top of the screen.
a. Go to MacHD > Applications >Utilites > and open 'Activity Monitor'.
b. In the activity monitor interface, select the Process Name ‘AvidAppManHelper’ from the column on the left-hand side, Then click the ‘X’ button at the top left to quit the process.
You should no longer have any ‘Avid Application Manager’ related processes in the ‘Process Name’ column of Activity Monitor.
2. Delete the following folders:
HD/Library/Caches/Avid/AppManager/Cache
HD/Library/Caches/Avid/AppManager/Db
HD/Library/Application Support/Avid/Licenses
3. Now once again go to Go to MacHD > Applications > Avid > Application Manager, but this time, double-click on the ‘AvidAppManHelper.app’ file and wait for it to appear in Activity Monitor’s Process list to ensure it’s started.
4. Restart Machine and launch AvidApplicationManager.app and then re-enter my Activation code and my System ID.
