Ah, I understand. Its more the broken link than needing a help file. Maybe bind the F1 key press event to:
ShellExecute hWnd, "open", "https://support.stardock.com/space/SS/1325531182/Start+Menu+Products", _
NullString, NullString, SW_SHOWNORMAL
This is what the 'Get Help' goes to in the about section of the app.
