My Windows didn't have the proper codec's installed to view the avi video files in windows media player. If you are having a similar problem you can get this file off the internet to update your operating system.
Media Player Codec Pack 3.2
Media.Player.Codec.Pack.V3.2.0.Setup.exe

After this was installed my camera worked very well.

If you need to install Windows Media Player, you can download it off the internet at:

I hope this helps,
PS. The manufacturer said that they are no longer shipping the cd with the pen camera. They said that Windows Media Player is a better viewing platform.
