PS Elements 2018 with Lighrroom

[#1]

Good afternoon!  I just purchased Lightroom and cannot get photos to open in my Elements 2018.  Any suggestions?  It asks me to browse to find the file, and when I select the location on my hard drive it pops up as unable to open.  Very frustrating.

Which operating system do you have? 

PS Elements 2018 is not supported by newer OSs like Catalina.  You would need to upgrade to PS Elements 2020.

You need to go to Lightroom preferences >> external editing to setup pse as an additional external editor
