I had this same problem. My solution was to uninstall Photoshop CC and then re-install from the website.
This worked just fine and then was able to apply the updates. I am using a PC with Windows 7

Please make sure all drivers on your system are up to date.
If it still fails then it seems your copy of PS CC is corrupted hence this message.
Please try uninstalling PS and then install it again from CC app.
After successful installation verify launching Ps.
Thanks everyone for yor help - Reinstalling worked - but this does seem a little like overkill - Imagine if you had to reinstall Wondows everytime you got an error
There must be a better way....?
