Any guidance here would be appreciated. Note that I might have accidentally loaded a Windows 2000 driver for this onto my computer but I would think the key for what Intel recommends would be the actual hardware and the actual operating system. Any thoughts?
I am sorry the utility did not give you straightforward advice. You can use the Windows 2000 file you reference. The driver you need is in there, and the installer will work in Windows XP.
http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=18717 has the latest software for Windows XP, but the driver for your device is the same one in the latest web pack for Windows XP. If you already downloaded the Windows 2000 software, you can go ahead and use that one.
We will also take a look at what went wrong with the update utility and get the bug fixed.
Have a great day!
