How to run IE6 and IE7 on the Same Machine?

After crying hoarse and loud for an upgrade to the much abused Internet Explorer, we’re now scratching our heads hard and trying to figure out how to run IE6 and IE7 on a single machine. The good news is, it’s possible, albeit tricky.

First install IE7 as is on your development machine.

For IE6, you resort to virtualization – first download VPC2004 (does not run on Windows Vista) or VPC2007 Beta (runs on Windows Vista). Next download this pre-activated Windows XP SP2 VPC image and use it with VPC to get a very felxible IE6 installation.

Included in the VPC image are:

  • Windows XP Pro SP2 + high-priority fixes through November 2006
  • Internet Explorer 6.0
  • Internet Explorer 7 Readiness Toolkit 2.0

You can make as many modifications as you want to the virtual machine running IE6 without affecting your IE7 installation.
