--- Comment #2 from Michael Müller <michael at fds-team.de> ---
You missed the most important fixme at the beginning:

fixme:wusa:load_assemblies_from_cab Cabinet uses proprietary msdelta file
compression which is not (yet) supported.
fixme:wusa:load_assemblies_from_cab Installation of msu file will most likely
fail.

Wine does not support the msdelta compression and therefore we can not process
msu files using this compression. See bug 12501, although the bug report is
about the older version of the msdelta compression (mspatcha.dll) while wusa
uses msdelta.dll as far as i know.
