How to merge Office 2K7 + Language Pack + Expression Web in one Instal

[Xajel]

Hi every one... I'm new member here so a Welcome will be great

any way, I've trying to Merge the Installation of Office 2007 Enterprise with Arabic Language Pack ( at least the Proofing tools, as they all I want ), along with Microsoft Expression Web with one install to save time of installing three packages...

all of them are using the same new installation system in Office 2007 with all those XML files, so I tried to merge them in one DVD and save the original CD's for backup.

but each time I tried a way it fails, at first, I tried to include the Arabic Proofing tools wich fails, then I tried to replace the Italian proofing tools with Arabic ones but it also fails, I tried to add Expression Web but also fails..

I found that I'll need more time to understand the exact way then new system works, but I don't have that time

any one can help here ??
