@SiMoNsAyS: Have tou tested this code? I just did a clean install of AcrobatReader7 (RyanVM's switchless version), followed by your cmd, and when I tried to open Reader7, I got this error: FYI, the file "Multimedia.api" is located in my: "C:\Program Files\Adobe\Acrobat 7.0\Reader\Plug_Ins" what's going on?
