after i downloaded windows 10, Lightroom stopped working. I have a Acer PC Laptop. It does NOT have a separate graphics card. i have already updated my graphics and have tried uninstalling and reinstalling lightroom 4 times and it is not working. I have contacted 3 different people from Microsoft and they said that the problem is on the adobe/lightroom side of things. Please help me
Please try the troubleshooting suggestions here: Adobe Lightroom GPU Troubleshooting and FAQ
If the problem persists please provide detailed information as to what is happening (or not happening) and any error messages you see. Also the LR version you are trying to install. (6.1, 6.5.1).
