One way to run multiple versions of Internet Explorer on a single PC is to run the older version(s) of IE using Windows XP Mode on a Windows PC running Windows 7 Professional, Enterprise, or Ultimate edition.
“Windows XP Mode is an optional downloaded feature of Windows 7 Professional, Enterprise, and Ultimate editions that provides you a pre-installed image of Windows XP SP3 that you run using Windows Virtual PC. A recent update allows Windows XP Mode to run on a CPU without hardware virtualization.”
It’s even possvible to set up and run multiple XP Modes on one Windows 7 machine, thereby allowing you to run IE versions 6, 7, 8, and 9 simultaneously on a single machine. The document embedded below provides detailed instructions for setting up a Windows XP Mode virtual machine and then copying it to create two additional XP Mode virtual machines and configuring them to run IE7 and IE8.
