I see you also posted in the other thread...
Have you tried this ...https://helpx.adobe.com/elements-organizer/kb/Elements-applications-do-not-launch-on-Windo ws-10.html it did not work for me ...
Not sure if anyone has contacted Adobe yet or just posting in the forums ...
In the other thread, someone posted that creating a 2nd user on your computer and using that account works..
It worked for me !
I signed out from my normal user and signed in with the 2nd and Elements fired right up.
Went back to the original user and still not working ... Strange.
This is a nice work-around, just wish there was a fix ...
I found a 'fix' ...
Something else I noticed about my computer was that I could not download anything to the default location of C:/Users/xxxxx - with the error saying you do not have rights ....
I started playing with the "Properties" of the Documents folder and no matter what I did I could not gain actual rights to it.
What I did to 'fix' was to;
Rt. Click -> Properties (Documents folder)
"Location" tab - - it displayed C:\Users\xxxxx\Documents
CHANGE that to C:\Users\xxxxx\New Folder (this is just temporary)
Windows will ask you if you want to MOVE all contents, say YES..
Now, test Elements and it should work (did for me at least)
Lastly, if you are like me, I want things the way they should be so I re-did the steps above and changed the location back to C:\Users\xxxxx\Documents and tested Elements again and it still works.
GOOD LUCK and feel free to ask any questions.
