OL2007 will not install if any other version of OL exists
And before you contemplate such you should ensure your PC meets OL2007
requirements

I have Office 2000 Pro installed and when I got the new HTC Touch Diamond
cell phone it came with a trial version of Outlook 2007.

Can I install it without losing my 2000 Version or will the install
overwrite it?
