Microsoft Office 2007 - total nightmare!

[kuzov]

Hello.

I want to slipstream MS Office 2007 in my Windows XP SP2 via svcpack.

I know there are several methods but:

-I find it overly unnecessary for 1 app to use runonce.

-I can't use RyanVM's update pack (I have modded some files and I don't want to risk them)

-Office 2007 needs Windows Installer 3.1 to use admin files, but I don't know how to slipstream Windows Installer so that it can be ready for use in SVCPACK.

Thus the question is: can I slipstream MSI 3.1 to be ready for use in SVCPACK stage, and if not, can I silently install it without admin files?

Thanks.
