Hey. I have LR installed that I bought and I just downloaded a new version of Photoshop which is a trial version. When I want to take my photos from LR to Photoshop, it wont let me. The field "edit in photoshop" is light grey and won´t activate.I have a brand new Macbook Pro
Moving to Lightroom forum.
You could set Photoshop as an additional external editor easily enough. But if you want it in the first position you might need to install Lightroom again.
