"could not complete your request because of a program error"

[l_dfkgjo]

I'm using PS CS6 and Lightroom 4.4 on  Win 7, 64 bit system.  I recently did a backup and when I went back to work Lightroom was fine but Photoshop was disabled.  If I click "edit in Photoshop" from Lightroom it gives the error message above with "that function may not be available".  I use it every day so that error message is in error.

When I just try to use PS CS6 standalone I can't load files or change preferences I get "could not complete the (whatever) command because of a program error".  Photoshop has completely gone disfunctional??

I'm also getting this error message: "AAM Updates Notifier App has stopped working" the cause being "App Crash".  I'm completely flummoxxed about where to begin here any ideas?

CS6 and LR 4 are discontinued and unsupported.  Use at your own risk.  I don't know why a backup would disable Photoshop.  Or perhaps you mean a system restore? 

If you still have your original disks/downloads and serial number, perform a clean reinstall after running the Adobe CS Cleaner tools.

Good luck!
