Okay after reading for about 2 weeks and everything I can about the OCT tool, I'm just about to give up. I had everything working where it was installing Office 07 from a dvd I created with all the serials and everything. It would upgrade the existing setup if there was a previous version and then install the updates and then project and visio. My boss asked if I could exclude infopath which I replied I could. From making that one change I haven't been able to chain any of the products anymore. I primarily used the OCT tool to chain everything. Office would chain to Project, and Project to Visio. The command line argument I used at the time would direct the install to go to the PrjPro.WW folder and use the config.xml. From there, I had nothing in the .xml files... it would read the .msp files for the info and would read that after install to run Visio installer. But I can't get anything to chain in any subsequent dvd I burned. It there a command or anything I should double check? Any help would be great. Thanks. Zac
