Clean install Win 10 on Dell Venue 11 Pro 5130 32 bit, can't find a useable WiFi driver

As subject says, can't find a WiFi driver that will install. I get to this page: Venue 5130 Pro (32Bit) 

Set OS to Windows 10, 32 bit and Category Network and get Dell Wireless 1538 Wi-Fi and Bluetooth Driver. When I download and try to install it the install starts and runs for a while then I get an error message about it not being supported on this hardware or setup (don't remember exactly what it said, I grab a snap of it the next time I try it).

I've tried the Compatability checker and run it as Win 8 but that didn't make any difference. Is it possible this tablet is 64 bit? If so, how do I check for that? Something in BIOS that will tel me? Even if it is, 32 bit drivers should work, right?
