Hello. Hope you are felling better.
From what you wrote, Premiere Elements just remained closed while you were away from it. Right? Any chance anyone else might have
been using it and made some adjustments? If not, then let us continue...
1. Let us try opening the program from the Adobe Premiere Elements.exe file.
Local Disk C
Adobe Premiere Elements 12
and then scroll down in the Adobe Premiere Elements 12 Folder until you get specifically to Adobe Premiere Elements.exe.
(You do not want the Adobe Premiere Elements 12.exe one).
After you get to the Adobe Premiere Elements.exe file, right click it, select and click on Run As Administrator. Then double
click the file and determine if that opens the program to the Premiere Elements Editor.
2. If I remember correctly didn't you have to uninstall the antivirus before the program would work? If so, maybe this time,
let us see if we can get away with just disabling "Real Time Protection" in the control area for your antivirus program.
Please try the above and, in the meanwhile, I will be preparing a check list for troubleshooting.
I followed your instructions in step 1 and it did open in the Editor?
I then tried it in my shortcut and clicked new project and it opened the Editor again?
Was I doing something wrong or is this programe testing me!!
There are several Premiere Elements challenges that go unanswered. Some have answers that we did not find. Some have workaround answers. For some, there are no answers that exist.
But, you have met this challenge. Great job.
Best wishes and hope that all is going well.
