Using Media Center and MCE to surf net on Xbox 360

[mistform]

I have been trying to use guides to surf the web on my Xbox 360 by using Windows Media Center and an add-on for it called MCE (Media Center Extender). Supposedly once I install MCE and connect the Xbox 360 to it I should be able to find an Internet button somewhere in the Media Center menu but I cannot find it. Someone suggested looking for a "Programs" in the Media Center Menu but I cannot find anything like it. I can't even find it in the "Options" for WMC via my PC.
I'm running 64-bit Win 7 Home with (as far as I know) the most recent updates for Media Center.

Any help is appreciated.
My gamertag is Schiztastic on XBL if you care to message me there.

EDIT: So far all I have found is guides for Vista. I also read on some forums somewhere about this not working for 64 bit Vista for some reason. I am not sure if the same is true for my 64 bit Win7
EDIT2: I looked at the Extenders on Media Center on my PC and it lists the 360 as "set up but not available". I can't figure out how to get it available. I've tried searching the net for the past 2 hours.

The Plugin which is used to open the internet explorer on the Xbox is not compatible with 64 editions of Windows. I have tried this in the past and eventually gave up on the idea because I didn't want to downgrade to a 32bit version of Windows.

Thank you for your answer. I still don't understand why it's incompatible. I run a ton of 32 bit programs. It's not like I need it to utilize the entire core of my processor. I just want to browse the internet on my Xbox 360.
