Does not include the 64bit driver. Also could you please name the source of the driver file?

Does not include the 64bit driver.

Yes it does, because this driver is both for 32/64-bits.

Also could you please name the source of the driver file?

I've unzipped both files and compared them with those on the DVD #1 (BootCamp stuff) that came with my MBP 4,1 -- they're identical. Note that the OP has a rev 03 wireless chip; the newest is rev 05. The zip-file isn't needed as all MBP 4,1 owners will have that DVD...

Yes it does, because this driver is both for 32/64-bits.

The .sys file is the actual driver... the inf is a descriptor and is valid for both 32 and 64 bits, but you still need the 64bit sys file. check on the dvd package.

It keeps telling me that its an invalid driver whenever I try to install it in the Windows Wireless Drivers app.

then you are not using the right driver for your hardware.

you can see the installed drivers with

ndiswrapper -l

using the names you see from the output of the above command, you can remove the "bad" drivers with:

sudo ndiswrapper -r drivername
