Re: nxt firmware not reading
It's not a Vista/Windows 7 thing. I've used Vista in the past (32 + 64 bit) and am using Windows 7 64 bit now. You did install the correct drivers? Ie 32 bit driver for a 32 bit system and the 64 bit drivers for a 64 bit system.
Are you running NXT-G at the same time? That wouldn't work as it tries to poll the brick constantly.
Download the drivers again and try uninstalling the driver and reinstalling from there. You can download them from this page: [LINK
