When trying to update Adobe Creative Cloud (Adobe After Effects CC 2014), the update might fail with Error Code: U44M1P7. All this means in that the update failed to install. Best solution: Reinstall the Application. This worked for me. TO Re-install:
Mac OS
Go to Applications/Utitlies/Adobe Installers.
Run the applicable uninstaller.
Windows Vista/7
Go to Start > Control Panels > Programs and Features.
Locate the affected Adobe Creative software title and click Uninstall.
