My PC rebooted (I assume a windows update).  I was using ON1 last night and today it will not start. I see the process running in task manager but I cannot get anything to start on the screen.

Any ideas besides uninstalling?

  What exactly is happening when you try to launch the program? Are you getting any kind of error message? Screenshots are helpful in those cases. Do you see the program's startup splash screen?

  If Windows did perform an update be sure to double-check your video card drivers. Windows updates are notorious for rolling back drivers to earlier versions. Be sure you have the latest version from the manufacturer's web site and they are configured according to "OpenGL 3.3 and Later is Required" - How to Update Video Card Driver (Windows Only) - Photo RAW.

  After that you can try the Delete Settings File function. That often clears up a lot of problems that appear suddenly.

  You need to kill the process that's running before you can restart the app. Reboot the PC is the easiest way.

  If it still doesn't start after rebooting, then Reboot once more and reinstall Photo Raw before trying again.
