Help Getting ARC On An Acer W4 Tablet

Hello. New to the Ez robot world and really excited to dig in. I've got my v4 and camera all ready to go but can't get the ARC software on my PC.

I'm normally a mac guy, but have an old Acer w4 running Windows 8.1. I downloaded the software, but when I go to install it I get an error that says it cannot be installed on a device with a .NET framework lower then 4.6.1.

I found some other people with this issue and instructions on how to update to 4.6.1, but here is the rub. Those updates are only good for x64 or x86 computers and the acer is a x32. I don't think you can go to 4.6.1 on a 32bit machine, but I could be wrong.

It looks like the ARC update to 4.6.1 is pretty recent. Is there anyway to download the slightly older ARC software before 4.6.1?

Thanks for any help anyone can provide.
