I have Photoshop CC installed in the Applications folder of my startup drive, as normal. I also have a backup drive online which backs up the startup drive each evening. LR 5.5 insists on using PS from the backup drive for editing, instead of the copy in the Applications folder. If I turn off the backup drive, it still refuses to start the other copy. How can I change this? Thanks...
That is a pain..
I am sure that I had to delete the Lightroom Preference File and maybe even the PS one to solve this.
You can find the Preference files through this link: http://helpx.adobe.com/lightroom/kb/preference-file-locations-lightroom-41.html
Do it with the back up drive disconnected.
Thank you - this appears to have done it. I never seem to think of the preference file! Also, since they let you pick the second program for "Edit In," what's the problem with letting you pick the first one? They don't think we're capable?
