You do realize Windows 10 is in Beta. Do you also realize you are not running the latest build?
Install LR on a Real, Finished, Complete Operating system and then post back if it locks up.
Yes I realize all that. My laptop is on build 10130, and LR and CC has worked fine on all the builds .LR has always worked on that.
but i have windows 7
updated lr to latest version started locking up when changing between photos.
up grade hard drive because i needed more room. fresh install windows 7 and installed lr newest version same problem still. befor i had no problem with the previous release of lr cc
shut off the checkmark for "USE GRAPHICS PROCESSOR" which is under PERFORMANCE in the SYSTEM PREFERENCES FOR LR.
To turn the Graphics Processor option off before starting Lightroom, read this link-
Thank you! I've tried everything else and it didn't work. THIS did.
