Hi Rolf,
I'm not sure I'm clear on what you're looking for.
Office Service packs use .MSP (path) rather than .MSI
files generally.
If you're looking for information on the Office Setup
command line switches for deploying the Service Packs
or for deploying Office XP you may want to check in the
Office XP Resource Kit at
http://microsoft.com/office/ork/xp
=========
Where can I find some information about the MSI properties built-in into the
different office msi installation files.
Thanks
Rolf >>
