I have updated my photoshop and get the following error - Extension Manager 6.0.8 Update Installation failed. Error Code: U44M1P7
Installation failed. Error U44M1P7 | Updates
But what I would do is restart your computer, and open the Desktop Application Manager as Administrator by right clicking its icon. Note this is with windows 7 and 8. I don't know how it works with OSX
