I use Parallels on my Mac to check CSS for my web designs in IE (Windows). I recently upgraded my IE browser to 7 and lost IE6 in the process. A Windows-user friend of mine suggested installing Virtual PC and pointed me to a disk image of IE6 that I could run on the virtual machine. After installing, when I try to launch Virtual PC, I get an error saying that my processor is too old to run VPC. Since I'm running this on a Mac with Core Duo, I think the error is incorrect. Does anyone know what the real problem is? Can Virtual PC run in a Parallels environment? Is there another way for me to use Parallels so that I can view my websites in both IE6 & IE7?
