I am using a PC. Whenever I go to check for updtes (click Help, then Updates) LRcc simply shuts down. It has been doing this for quite a while, I have opened closed, shut down the computer maybe 100 + times over months. I did not want to do anything that would cause me to lose LR until a major project was finished but now I am ready. Any ideas what is going on.
Please try turn off the Graphics Processor from Lightroom preferences.
Go to Lightroom Preferences from the Edit menu
Click on Performance tab
Uncheck the Graphics Processor
Let us know if that helps.
