Officially, this is the last version of Office to work with Windows 2000, however, if you use BlackWingCat's Extended Kernel, you can install Office 2007 or Office 2010 on 2000, but you'll have some minor bugs (such as problems with the classic interface) that don't appear to affect anything major.
