Thanks! That's exactly the kind of list I've been looking fore but not been able to find. Do I always only have to install the latest hotfix, for let say Word, or do I normally have to install all the previous hotfixes as well? Example: Both wrd1005a.exe and officexp-kb824934-fullfile-enu.exe contain a file named "winwordff.msp". Do I only have to install the one from the newest hotfix? Is this perhaps why you beleve that the newest word and excel hotfixes supersedes the older ones? The instruction for the slipstreaming of hotfixes ( in the file OfficeXP_Slipstreamer.cmd - se the quote from the file below ) seem to targeting two different msi-files. Mostly it targets the proplus.msi but at one occation it targets the owc10.msi. If I want to slipstream more hotfixes, how do I know which msi-file to target? //Mattias
