This semester I'm going to need to run AutoCAD on my MacBook Pro, and I've decided to run it on Windows. I don't yet have Windows on my computer. Here's what I want to do: Download the trial version of Parallels Download Windows 7 onto the VM Download AutoCAD (should be free) Test to see if AutoCAD runs fast enough through Paralells. If it does, buy Parallels. If it doesn't, remove the VM and create a boot camp partition. Install Windows on the partition. Download AutoCAD again.Can I do this with one copy of Windows 7? Can I do it with a downloaded copy (no disk or anything)? What about with an upgrade? Through my college I can get a "Windows 7 Professional Upgrade" for $65.55. That price is for an internet download, but I can get it through mail order for a little bit more: Hopefully this link works. Could I use that to install windows on a VM or separate partition? It's no big deal if I need to buy a full disk version of Windows 7 (64-bit Home probably) to do this, but I need to act soon. Thanks for reading.
