GPG4WIN won't even install.

I’ve been trying to install this program ever since yesterday and it just will not work. I’ve read SO many tutorials and need this to work BAD. I only attempted to download the main program (GnuPG) and get all the way to the end of the installer but I only see a bunch of invalid files when I try to access it. If this does anything, my computer is a Toshiba Satellite L675.

I gave up on GPG4WIN and bought Symantec PGP Desktop instead. If you want a dependable solution you can actually install, you should probably do the same.
