After downloading the Firefox 7.0.1 installer, running the .exe, it extracts the installer, then provides a small windows login box, looking for Admin permission. Upon logging in to provide permission, the process abruptly ends.

It is possible that your anti-virus software is corrupting the downloaded files or otherwise interfering with downloading files by Firefox.

Try to disable the real-time (live) scanning of files in your anti-virus software temporarily to see if that makes downloading work.
