PSE 15 Launch Issue

[ronb19316473]

I downloaded PSE 15 from the apple app store.  I have installed the patch for fixing the launch issue.  It still doesn't launch.  Any fixes I can try.  I am running it on a late 2011 MacBook Pro with Sierra.

Try trashing the prefs. Hold down the there keys Cmd+Optn (alt)+Shift and then double click on the icon or on the app in Finder.

Photoshop Elements Editor

Keep the three keys pressed down for two or three seconds and then release.

When you see the pop-up click on Yes and then wait whilst Elements rebuilds the default prefs.

Sorry for the inconvenience.
As suggested above, keep Cmd + Shift + Option keys pressed while launching Editor. Clean the preference settings file when asked for.

Let us know if issue still persists.

Thanks,
