Opening a .pdf file in PSE 15, through "edit in" in Lightroom

[NootkaRose]

The following message pops up. I'm running OS X Version 10.6.11. How can I fix this? Also, the usual icon for PSE 15 does not appear in my applications folder or in the dock. A generic icon appears instead. Can anyone explain why.

Many thanks for any useful suggestions.

I the Lightroom Preferences>External Editing point to the

Adobe Photoshop Elements Editor.app

in

/Applications/Adobe Photoshop Elements 15/Support Files

The message you got usually happens if the External Editor is pointed to the

Adobe Photoshop Elements 15.app

in

/Applications/Adobe Photoshop Elements 15

Many thanks for the solution, and for your prompt reply, R_Kelly!
