This visual tutorial might be of interest to you.

Though, it does sound like you have a corrupted file or bad download. 
You could try downloading it again, downloading it again, etc.  Also 
download the md5 file from rubyforge.  You can check the md5 sum of the 
file with a program like this.

I also wouldn't rule out spyware, viruses and other malware.  Sometimes 
they try to modify executable files as they're downloaded.  Run spybot 
or something and try to check that out.  There are a lot of things that 
can go wrong, you just need to start ruling things out.
