Windows 7: Install MS 2007 But Keep MS2010

I have 2010 already installed but I want to installed 2007 and 2003 versions as well.

I'm told I need something called MPS Config???? (how to obtain)

I have seen a couple of articales on this but I tend to glaze over a bit.

Anyone know of a simpler way to achieve the above.

Thank you all

I have to ask why do you want to install older software? Any way, create a System Restore Point then see what happens if you just try to install from the 2003 or 2007 discs?

You have plenty of memory to virtualize, so depending on your needs, you might want to consider virtualizing two older copies of Windows XP, and installing each version of Office in there. No conflicts to worry about, and if you were testing out something, you could compare all three versions at once, with your native system and two VMs running.
