Do you have TheSkyX installed on your system? Is it possible you installed it after Planner? If you do have TheSky X:

  1. Find TheSky.exe, right-click, select Run as Administrator. Allow it to completely start up.
  2. Exit from TheSky and never run again as Administrator
  3. Re-run the ACP Planner installer. <-- direct link to installer

Now Planner should show desktop icons for the Capture apps, starting Plan or Quick capture should automatically start TheSky, and all of this should be inder ACP Planner in your Windows Start menu.
