Dude you are in luck. I just did one. I used this guide posted in the "Office Shrinker" forum posted above(Click the first link by Booogy). Here it is. Someone should make a PDF of this cause its a brilliant guide. I used Xable's OfficeUpdater to simplify the slipstreaming process. OfficerUpdater The only other thing i did was intergrate Frontpage 2003. Oh and also integrated the updates released since then. This was a little tricky. I had to make a .cmd file and point the Config.txt to it. So the Cmd file contained the lines> setup.exe TRANSFORMS=Custom_Setup.MST /qb- Frontpage2003\setup.exe TRANSFORMS=Frontpage2003\CustomFPage.MST /qb- to run the silent installer and the config.txt looked like this. ;!@Install@!UTF-8! RunProgram="run.cmd" ;!@InstallEnd@! You need to use the CMD file cause you can't do multiple RunPrograms in the config.txt NOTE ALSO: I wasn't able to shrink frontpage. Don't know if its possible. Probably because its separate from the main Office package. My pre-compressed source was 730mb After 7zip Compression 243mb Sweeeeeeeeeet!!!!!!!!!!!! Hope this helps man Good Luck PS: Forget about CAB. Silent Installer is the way to go for this type of addon. The extra compression it gives is a must it you want to fit it on one CD.
