Premiere Elements 15: "Edit Original" is greyed out.

[labguylarry]

Greetings: I just migrated my Premiere Elements 15 to a new PC. Previously, while making slideshows, I could right click on a clip (still frame really) and "edit original". This would switch me over to an old legacy permanent licence of Photoshop CS 4 where I could edit that image. After migrating, I only have "edit in Photoshop Elements" available. "Edit Original" is greyed out. Keep in mind this worked previously - the old and new computers are both Windows 10. I am running Classic Shell, but I expect that shouldn't matter.  How can I get back "edit original"?

I was not aware the choice was even a possibility!  That would be really useful!  I checked and mine is the same. 

The "official" instruction manual is here:  https://helpx.adobe.com/pdf/premiere-elements_reference.pdf

I did a search on "edit original" and got seven hits.  One says:  "Edit a clip in its original application --- Some files contain embedded information, called a project link, which indicates the application in which they were created. Adobe Photoshop Elements, Adobe Audition, and Adobe After Effects® create files with project links."

I hope someone comes up with how to create "project links" in Photoshop versions including CS4!
