I have today upgraded my Dell to Win10. I now find that Lightroom CC crashes every time I try to click on Edit>Preferences (or Help>System Info for that matter). Suspecting a graphics driver issue I made sure my graphics driver (Intel HD Graphics) was current. I have reset Lightroom preferences (ALT-SHIFT-Lightroom), but neither of these methods works. My next step was to follow the advice here Adobe Photoshop Lightroom Help | Lightroom Graphics Processor Acceleration (GPU) Troubleshooting & FAQ but the line specified to be edited (useAutoBahn) does not exist in my Lightroom 6 Preferences file.
In short, I cannot access Edit>Preferences to untick the graphics box and I cannot do a manual edit on the Preferences file. So I am stuck in a situation where the program crashes when trying to change my preferences. How do I get around this?
It is usually near the bottom when viewed in Notepad.
