Great guide! I just thought it would be nice to share my idea that just struck me. I needed my addon to get a smaller final size to fit in my XPCD. My Office CD is in swedish so I couldn't use the "office shrinker". Here's what I did: 1. Copy the Office2003 setup folder (after nr. 4 in post 1) to a shared folder that you use with your virtual environment (virtualbox, vmware...) 2. Install Office2003 from the setup folder in your shared folder (using the commands described in (5) in post 1) in your virtual environment. 3. When the install is complete, search for all files (*.*) in the Office2003 setup folder and check the last accessed time on the files. 4. Delete all files that weren't accessed at the time of the Office2003 install! 5. Continiue at (5) in post 1! Tested and working! My addon just shrunk from 206mb to 112mb! Edit: The addon worked flawlessly Edit2: Tried to clear things out, my writing sucks
