I think several people may be experiencing the same thing. I am a CC member and have Photoshop installed along with its regular components. This morning I received the notification that updates are available. Updates for Camera Raw, Extension and Bridge all update today with out an issue, but not Photoshop - I received an Update Failed message. I attempted to reinstall the update no dice same message. I looked at the logs which stated there was a file corrupted and had to uninstall the application. Did both those steps then proceeded to the update. Again Raw, Extension and Bridge update with no issues, but the same Update Failed message from Photoshop.
Is there a solution to this yet or is there a fix Adobe needs to make to the update package?
May i know the exact error message and the operating system details?
