An automated installation of video codecs ;-)
- Xvid (plays divX also)
- AC3 (5.1 Dolby Digital)
All a newbie could ever need to play his or hers avi files!
PS! If you are unsure about opening an exe file then unpack it with WinRAR and install manually (you may even read the "source" code) and validate that it is not a fake. Right click the file and press Extract to manually extract.
