Didn't ask to add gmail account

So I just flashed CM7 build 43. Everything went fine and phone booted up. I didn't do the normal thing of going to the android thing and saying tap here to start or whatever. It just went straight to my home screen. The market isn't even installed on my phone. So I figured I had to install Gapps so I dl'ed and tried to to that, but everytime I try to install it I get this "signature verification fail Installation aborted" Any help will be greatly appreciated.

 

I got it to work. I went to the wiki and dl'ed the file from there, and it installed fine.
