Can Microsoft Office 2007 be installed on system with Office 2010 already installed?

Question

I have a Windows 7 machine with Office 2000 installed.

I am doing some development with Outlook Add-Ins and I installed Office 2010 Professional Plus. Development of this add-in is going fine.

My client may delay upgrading Office 2007 to Office 2010 so I would like to install Office 2007 alongside my current installation of Office 2010 and test my Add-In in the older environment.

I can configure Outlook 2007 to use a different email account than that used in Outlook 2010 (i.e. this is strictly for development testing; no need to share a .pst file between versions).

Is this possible - or must I un-install Office 2010 (Outlook 2010) in order to test with the older Office 2007?

With Microsoft's App-V, many things like this are possible

Because each Outlook version uses its own version of MAPI, you cannot install more than one version of Outlook on any machine. This is also true for anything else that requires MAPI components like BES or Exchange 2003. If you try to install Outlook on a machine with BES or Exchange 2003, you break something because of the MAPI version mismatch.

Isn't this more of a StackOverflow or SuperUser question?
