[MB Air 2013] Windows 8 says I need a Boot Camp driver update, but download is unsupported

Hi all,

I'm on a brand new 2013 MB Air running Windows 8 64 bit with Boot Camp.

Windows is running fine, but I just recently noticed that I had a message telling me I had a driver missing and needed to update Boot Camp.

Now, this computer is less than 1 week old, so I checked my Boot Camp verison first and it does say that I'm running Boot Camp 5.

Just to compare the drivers, I downloaded the suggested update (from Apple, Boot Camp 5.0.5033) and put it on an extra USB drive.

When I compared the drivers, the new download did contain significantly more drivers for various hardware(most of which I don't have), so I tried to run it from the USB drive.

At that point I got the "Boot Camp x64 is unsupported on this computer model error".

I'm running Windows 8 64 bit, so I don't see why BCx64 is unsupported, and I'd really like to get the "driver update needed" message resolved.

Am I being directed to the wrong dowload? Do I even need this one?

Should I be running an update through OS X even though the message is coming from Windows 8?

Any ideas on how to proceed would be appreciated.

Thanks!
