Office 2011 is a common application to get baked into an InstaDMG image (or any other pre-compiled, modular style image). There are a few quirks to installing Office 2011 in this way as it was made to be installed on a live system. Noel Alonso put a script together that fixes some of these issues on the Office 2011 SP3 Installer. These changes help it install correctly and also fix some bugs with the installer itself. You can take a look at the script over on Noel’s Blog.
