I'm not adding any updates or patches. My "Update" folder is empty. Anyway, if I choose to install Office 2007, the WPI gives error. Only if I install Office 2007. If I choose to install ALL the others applications, the installation went well, without problems. I'll attach an screenshot of my WPI configuration. ___________________________________ EDIT: I've found a REALLY PARTIAL solution. I've moved the Office installation to the bottom of my config.js file. The installation of Office corrupts WPI with the next installations, so I decided to move it to bottom to resolve the problem. See you around!
