Hi,
After opening Photoshop and getting and error message go to the Start screen and type 'view event log'. Select choice. Select windows logs > applications from Event viewer window. Search for a red exclamation mark and description of error. Mine indicated a driver issue. Even thought I updated the driver to my graphics card it still didn't work. I copied the driver indicated to another folder: windows/SysWOW64. This has fixed the issue for myself.
