Nothing happens

[Balled]

i downloaded the .net 2.0 and then i downloaded the auto updating map package. when i click on the file nothing happens....i get the hourglass for a few seconds and then it goes back to the arrow. same thing happens when i try to install vent. ive tried changing the names to .exe but still nothing happens. im sure this is a really easy fix but i cant figure it out lol...would appreciate any feedback.

You need to UnZIP the arcive first, then run the installer
