Vista and Office 2000 or 2003

Hello Friends,

I have Vista and (strangely) office 2000 premium on my notebook. To convert office 2007 files, i tried to install the office 2007 converted. It requires office 2000 SP3. But Sp3 can not run on vista as it is a 16 bit program. What is the solution.

Further to install SP3, I needed to install SP1R. This got installed but everytime i start word or excel it starts to install again and report that the file "seetup.hlp" is not found. I searched in my comp and the web, I could not find this file.
