Did you make sure you got the drivers installed properly? Also, you might want to go into the device manager and disable the built-in wireless card to make sure there aren't any conflicts that was preventing the USB adapter from working.
I didn't even get a popup saying I had to install anything. :/ It worked on my little sister's laptop just fine, and her built-in wireless card works just fine. Otherwise I wouldn't be able to post this. :/
