ok many thanks Astalavista

and many thanks for your guide

sorry Cartoonite

but if i remove the IERunonce.dll

the installing well not run immediately

It would run immediately if you replaced your Office.exe file with one created from the code I posted. Instead of importing the installer programs into the registry to be installed one at a time, the installers are called one at a time from directly in the executable itself. IERunonce.dll can be used if you want to execute the RunOnce key without having to reboot. Calling installers directly from the second executable file rather than importing a new set of reg entries seems a simpler solution to me.

If, however, you can get everything shrunk down small enough to fit on one cd by making use of astalavista's posted 7zip Office guide, that's an even simpler solution. Plus, as an added bonus, the install can once again be 100% unattended.
