I have this exact issue with my Windows 7 machine. TARGET works fine for me on Windows 10 but not Windows 7. I have been shutting down background programs and still no joy. I am not running Afterburner or Riva apps on either machine. I have tried all the compatibility settings and running as admin but it still gives the “TARGET is not Working error” with no reason as to why. There should be a law against an error message that doesn’t give the user a clue. It use to work on both machines. I wonder if a Windows Update patch is causing this. Any clues guys would be appreciated.
Thanks,
