Can I install Office on two partitions of the same computer?

[William Low]

I have Office 2007 on XP, but I may want to try installing Vista on a
separate partition. Can I take my Office 2007 installation disk and
reinstall it on the Vista partition while keeping it on the XP partition?

Here is an example, you may need to modify some steps.
