I actually own the new Photoshop Elements 15 Win10 App and I don't find any possibility to integrate it in LR because no corresponding .exe file is available in the standard folders.
Encounter somebody the same problem and can help me to find a solution.
Thanks you in advance for any advices about this issue.
If you purchased PSE15 from the Windows Store it’s a container installation and it may not be possible to set up the Editor for external editing. I suggest you contact Adobe directly using on-line chat. It may be necessary to ask for a product switch either from Microsoft or Adobe
