I have Office 2007 Enterprise without SP1. I have downloaded the SP2 file, extracted the MSP files, and placed in the Updates folder. However, I cannot find out if SP2 includes SP1, or if I need SP2 & SP1 MSP files in the updates folder. Or, does it not work unless I have a SP1 Office 2007 CD? Also, after SP2 install, is there a list of other updates that are still needed that I should include? Thanks for the help.
