Hi I have Office 2007 Enterprise Ed, I work at a University here in South Africa, I need a script to do a silent, customised, full (with all the bells and whistles) unattended install for 400+ PC's currently running Office XP Pro and Office 2003 Pro. It would need to remove all previous Office versions etc. I'm not too concerned about the files that are cached on the local machine, I'll use a batch file to sort that out. I will run the office installation from a network share. I haven't worked with scripts alot as they always seem to need lots of fiddling I'm hoping someone has a script already that I could use and edit a few parameters like cd key, company and user details. Any help would be greatly appreciated Thanks
