I think I have the majority of WPI figured out, and I have been tweaking an installer for my specific needs. However, I have something of a project for work that I'd like to get some assistance on. We support multiple customers in a break/fix environment. Many of these customers have their own subscriptions to msdn, vlk, and other licensing agreements for Office 2007 and 2010. I'm trying to find the best way to completely automate their installations so that it includes their license key, but I would like to only have to use 1 usb stick and only 1 copy of each flavor of the office installers (pro, pro plus, bcm, enterprise) on it. I can use the admin tool to create a seperate .msp installation file, but what I am trying to figure out next is how to use WPI to assign a specific .msp file to a specific customer. At the moment, I have created about 15 different configurations. Each one is named for one of my customers that I typically install software for, as well as a default installation configuration for the one-off installs. The default install cannot automatically place a license key into the office installation, as that would cause problems with licensing down the road. I'm hoping that this makes sense to others, and if anyone has an idea of how I can configure this, it would be greatly appreciated. If you need more info, please let me know and I will do my best to explain in further detail what I am trying to accomplish.
