The U44M1P7 error indicates that the update wasn't applied. The common cause for most users is the removal of additional language files from the software installation. The update fails when it can't locate the appropriate files to update.
System optimizer applications often remove the additional language files. If you use these types of applications regularly, adjust the settings so that they don't affect installed Adobe creative applications. If the language files are removed again, it's necessary to remove and reinstall the Adobe creative applications to restore the language files.
