Quite often I need to install Office2k7 with default English interface OR with Croatian Language Pack. As a rule there is (almost) useless internet connection. So i compiled two sets of installers, (1) SP1 + all the patches for English version and (2) Language Pack + localized SP1 + Language Pack SP1 + all other patches for Croatian version. Now, it was pretty straightforward to compile "slipstreamed" DVD in case (1). It is the case (2) i don't really know what to do.
