I am very frustrated with Microsoft right now. I currently have a Macbook Pro with Retina Display and want to install Windows 8.1 in virtual box. I went to the MS website and was a little confused about the options so I started a live chat for help. They told me to purchase the Windows 8 Pro and after the purchase, I would be able to download the file for virtual box. I did all this. The downloadable file turned out to be an .exe file that I can't run on my Mac and I need the full iso for virtual box. I contacted them again and they just keep telling me to download the .exe file. I even tried to explain to one of them its not working and they abruptly ended the chat. This has been beyond rediculous so far. There are so many people that somehow manage to install Windows on their Macs using Parallels, Boot Camp, Virtualbox, etc. - its not like I'm the first one. It doesn't seem like I can get an ISO any other way except as a torrent. Can someone please point me in the right direction?
