Can't install Canon MG6620 drivers

I had a complete Windows crash and had to reinstall it from start. When I tried to install the drivers for my Canon G6620, which worked perfectly fine before the crash, it hangs up.

First, even though my printer is turned on, it stops and tells me to connedct the printer to the computer and turn it on. So I turn it off and back on. Then it says "the printer is detected. please wait until installation is completed" Except it doesn't TRYto compelte the installation. IT has been over 10 minurtes. Nothing. And in the task manager, the Canon process is at 0 across the board. No CPU, no memory, no disk.

This happened with both the CD that came with the printer, AND the driver downloaded driectly from the site. And to be clear, both my Anrti-virus and firewall were turned off when I attempted this.
