In trying to correct a problem with Lightroom trying to find Photoshop CC 2014 when I clicked on it in the Edit In menu I ended up with two entries for Photoshop CC 2014. And when I click on either one it wants to open as either a PSD or TIFF file rather than than a raw file with the LR adjustments. I have tried reinstalling both Photoshop and LR without any success in correcting the problem. What are my next steps?
Have you installed Camera Raw 8.7? If you have Camera Raw 8.7 and Lightroom 5.7 then you shouldn't get that message asking you to create a copy. But in either case, once the editing in Photoshop is completed a TIF or PSD file must be created. Whichever file type is saved depends on your preference settings. Photoshop is not capable of editing or saving raw image data. By the time the image has been opened in Photoshop is no longer raw image data and must be saved in a different file format.
