Photoshop Elements 15 don't work in my Win10 System

Do not count on Windows to be fully up to date when it comes to device drivers

Go to the vendor site to be sure you have an updated driver for your graphic adapter

•nVidia Driver Downloads http://www.nvidia.com/Download/index.aspx?lang=en-us

•ATI Driver Autodetect http://support.amd.com/en-us/download/auto-detect-tool

There are also intermittent reports that the newest driver is not always the best driver due to driver bugs or compatibility issues, so you MAY need to try an earlier driver version

2nd, Dual video problems - Do you have dual graphics adapters?

Go to the Windows Control Panel and select Hardware and Sound and then select Device Manager... In Device manager you click the + sign to the left of Display Adapters... and see if 2 are listed

IF YES, read below
