If what you want to have is an unattended installation, BUT that WILL (eventually) ask for a product key, you should add a registry command (in any form you like, e.g. batch file/command line and/or .reg file, etc.) that will erase the following values from the registry: HKLM\SOFTWARE\Microsoft\Office\1x.0\Registration\{xxxxxxxx-xxxx-xxxx-xxxxxxxxxxxx}\ProductID HKLM\SOFTWARE\Microsoft\Office\1x.0\Registration\{xxxxxxxx-xxxx-xxxx-xxxxxxxxxxxx}\DigitalProductID This way Office will ask for a product key the first time you run any of it's products. Only problem is - I think {xxxxxxxx-xxxx-xxxx-xxxxxxxxxxxx} is a unique string on each machine (someone please correct me if I'm wrong), so you must find a way figure it out if you wanna do the deletion part automatically... Hope I helped, in a way... Keynan.
