LR Classic can't edit in photoshop cc

I was having a very similar problem to that described by the OP, namely, whenever I tried to use the "Edit In..." command from LL Classic, hoping it would allow me to continue editing that single image in PS CC 2018 (64 bit). 

Unfortunately, nothing would happen for 4 or 5 minutes, then LR usually put up a window saying that "LR couldn't open PS CC 2018".  Then, much to my surprise, as soon as I clicked, "OK", to get rid of that warning window, PS CC 2018 opened, with the image from LR displayed properly.  This behavior was not entirely consistent, in that sometimes, PS would never start (or maybe I just didn't wait long enough).

Since I really wanted to be able to use the convenient "Edit in ..." command, I've been looking around for a solution to this.  I just tried a suggestion by Jeff Van de Walker (apparently, an employee of Adobe) from the following thread and it partially worked. Link:

Lightroom: "Edit In..." no longer works consistently in Lightroom 5.4 | Photoshop Family Customer Community ​

His suggestion was to add a text file called config.lua to the LR presets folder.  In my case (Win 10), this folder was at:

C:\Users\TJM\AppData\Roaming\Adobe\Lightroom .

I added this file, and PS 2018 (64 bit) would immediately start up.  Unfortunately, no image would be displayed by PS.

This is driving me crazy.  If anyone has any suggestions as to what may be going on, I would appreciate it.

BTW, the LR "Edit in" command was working absolutely fine until I manually installed a copy of PS 2018 (32 bits) a couple of months ago because I needed to use some of my very old favorite plugins.  When this happened, I tried uninstalling both programs, cleaning out any left-over debris (using both Revo and CClean), and reinstalling all three programs, LR, PS 2018 (32) and PS 2018 (64 bit).  I tried installing them in different orders, and it mad absolutely no difference.

Thanks for any light you might shed on this.

Same problem, software just updated.

I am not having the same problem - did you ever find an answer?!

Hi. I am having exactly the same problem. Following the actions in the "'Edit in Photoshop' command missing" hasn't worked. I have just installed Lightroom Classic CC and then updated Photoshop to Photoshop CC 2018.

Hi masktao,

Please refer this article 'Edit In Photoshop' command missing and let us know if the solutions listed helps in opening images from Lr Classic to Photoshop CC.

Also, Which version of Photoshop are you using?

Thanks.
