Okay, what you do is this.
1. Download the file
2. Open it
3. Extract any files (if necessary, you'll know if you need to extract it if the file has a zipper on it)
4. In another window, open up http//:Program files/microsoft games (try a couple times with different names similar to this. For example, http:// or http/:, etc.)
5. a window should appear with a number of files labeled 1001, or similar.
6. Now go back to your extracted file. Copy it.
7. Paste it in the program files window
8. If there a few files in the extract window (one with a zt2 logo, one with an installation looking file, etc.) make sure to copy them all.
This should work. It's all trial and error, of course, so try with a few different downloads and try to work through the process different ways)
