Bypass the Unwelcome Screen by creating Desktop shortcuts for the Organizer and the Editor, and restarting your computer.
The Editor's executable is:
"C:\Program Files (x86)\Adobe\Photoshop Elements 10\PhotoshopElementsEditor.exe"
The Organizer's executable is:
"C:\Program Files (x86)\Adobe\Elements 10 Organizer\PhotoshopElementsOrganizer.exe"
The Unwelcome Screen leaves a zombie process running which prevents the actual program from launching again.
Is there a similar work around for Premiere Elements 9? I could not find one in the forum for PE9.
I couldn't tell you, since I don't have PRE installed. You can try searching for its executables under .\Adobe....
