- Launch Task Manager (Windows) or Activity Monitor (Mac OS).
- In the Task Manager/Activity Monitor, End Process/Force Quit the following processes if you find them running and then try to delete the OOBE folder or empty the Trash:
- AAM Updates Notifier
- CoreSync
- Creative Cloud
- Adobe Muse
Note:
For more information on ending running processes or programs, see the following:
- Mac OS: Force an app to close on your Mac
