I'm getting an error when trying to open lightroom, "You cannot open lightroom app because it's not responding". This has been going on all day. I'm not sure what to do, help!
Please disable the Graphics Processor for the machine and then turn it off from the Lightroom preferences.
Go to Control Panel >> Open Device Manager >> Under the Display Adapter >> Look for Graphics Processor >> Right Click on it and disable it.
Now, Open Lightroom
Go to Lightroom Preferences from the Edit menu
Click on Performance tab
Uncheck the Graphics Processor
If the Lightroom works fine, then go to back to the Device Manager and enable the Graphics processor.
Let us know if that helps.
