How about Packages --> Install package(s) from CRAN...? You are making 
things unnecessarily difficult.

Zip files don't end with .tar.gz! These are tarred and gzipped source 
packages that you are almost certainly not set up to install. Your best 
bet is to try the simplest things first, which on Windows is to use the 
Packages menu.
