I have never been able to use Lightroom CC desktop version. The application crashes on startup. I suspect this has something to do with my GPU. I had to disable GPU in Lightroom Classic CC, Photoshop CC, Camera Raw CC, to be able to use these applications. However, I cannot do it in Lightroom CC desktop, because it has never started so far. My Lightroom CC preference folder, C:\Users\[UserName]\AppData\Roaming\Adobe\Lightroom CC\Preferences is empty. There is no preferences file. Is there a way I can download a default preference file? I am on Windows 10, current Lightroom CC version is 1.4. None of the suggestions on this forum, including he one to reset preferences to default, by starting with "Alt"+"Shift" key pressed, have worked so far.
