Try these solutions to see if any of these work.
If none of them works, let me know.
Close Elements. Launch the Photoshop Elements Welcome Screen and hold down ctrl + alt + shift as you click Editor. Continue to hold the keys until you see a message box asking if you want to delete Photoshop Elements settings file. Click Yes. Elements will open with default preferences.
In case any network printer is attached try to launch without network or printer uninstall or make different printer as default.
In case that does not work too, you may try this.
Try launching with anti-virus off or removing PSE from conflicting list.
My PSE11 Editor stopped launching after updating the Adobe Application Manager. Will launch if I restart the computer OR if I stop the PSE Editor.exe PROCESS in the Task Manager. All this after running normally for over a month UNTIL I DID THE AAM UPDATE. Re-install X2 did not help. Can't uninstall AAM- tried the Adobe Creative Suite Cleaner Tool-no help. Also, reset preferences/d/c printer and Anti-Virus soft ware-no help. Thoughts? BTW- checking for updates only showed AAM and Raw updates. NO Help either. Yuck!
Adobe help provided direction by CHAT Response that SOLVED my PSE11 Editor problem (Win 7 Pro 64 bit): C:/Program Files (X86)/Adobe/PSE11/PSE11Editor.exe-RT Click/Properties/compatibility/ check -Run as Administrator. Check the -use these Settings for all users -click- the change that to Run as Administrator - which is on the next screen.
Do the same for PSE Elements11.exe and PSE Organizer.exe (in order for the Organizer and the Splash screen to work too.
After this exercise- PSE11 Editor and Organizer has run flawlessly.
It is such an improved program-it is worth the effort.
