UR 22 driver issue

“The processor is not adequate for running Yamaha Steinberg USB driver.”
I know the answer is going to be you do not support it running virtually but I am running Windows 8.1 as a VMware virtual machine on a new MacBook Pro and that is the error I am getting. I have done all the latest windows updates but still getting the error. That is the error on the 32bit driver. The 64 bit driver loaded fine but I am not ready to run 64bit and have a load of my 32bit plugins not work.
