I was running PP 1.9.8 in a VM under parallels (on a mac) and was able to install PP 2.0, but I had to create an ISO file from the USB Drive it shipped on and then install it from that. Once you get it installed, PP 2.0 runs even smoother under sim mode than 1.9.8 did. I think they tweaked a couple of things. First, the zeroing (referencing) seems better. I had to turn off the homing switches before, but now it works correctly right out of the box. Also, the mill lathe selection screen appears when you start it up each time. All of the functions work, including the update over the internet, so now you don't have to fool around with mounting USB drives on your VM. It has been quite handy being able to experiment with the conversational tabs in my office, as well as testing Fusion 360 code.
