I've just downloaded Lightroom CC (2015) onto my computer, it says it has downloaded, but every time I try to open it, it says, "Adobe Photoshop Lightroom has stopped working" It tries to fix it, but it never works then it says "A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available." Then I'm forced to close the program.
Which OS version are you using?
Kindly try to update the Gpu driver and respond if that works. Awaiting your response.
