avr pocket programmer problems installing windows 64 bit

hello I am having trouble getting my avr pocket programmer to work http://www.sparkfun.com/products/9825

I am running windows 64bit and pluged it into my computer and it seems to install drivers automatically so when I try to update the drivers to the ones sparkfun has on the website it says the windows drivers are the best drivers and will not install then. ok so im assuming then I dont need to install the drivers from sparkfun but when I go to my device manager I cant seem to find what com port its on. here is a screenshot

The web page includes notes on using it with Win 7 x64.
