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.
Windows 8
- Press Windows Key + R to open the run command. Type Control Panels and press OK.
- Open the Program & Features Control Panel.
- Locate the affected Adobe Creative software title and click Uninstall.
