Wouldn't it be better to detect eMule using DetectFile=%ProgramFiles%\eMule\eMule.exe as many eMule mods only comes as binary files and not with an installer. I say this because I've experienced having eMule in the Program Files\eMule folder but not in the registry. So to get these 2 entries to work I had to manually create a key in the registry (HKCU\Software\eMule).
