Ok, I think I will try the Chained Install. The Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats has a service pack available, Microsoft Office Compatibility Pack Service Pack 1 (SP1). Would I do a Chained Install with the Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats then the Microsoft Office Compatibility Pack Service Pack 1 (SP1), or could I somehow slipstream SP1 into the Compatibility Pack, then add the slipstreamed version to the Chained Install. Also, what is a silent switch, I am pretty new to all of this slipstreaming stuff. After I make all of these files, I can just burn the contents of my new OFFICE11 folder to a CD then run Setup.exe from the disc and it will install right? Or do I have to use some type of ISO program? Thanks.
