Steven is correct.  This should provide you with more info. It would be useful for the record and others that come after to report back what this shows.

For any msi file (Shibboleth or other) the way to get an installation log is via the /l qualifier.

	msiexec /l log.log /I installation.msi

My experience is that will give you enough to be going on but there are extra qualifiers to give greater levels of logging.

If the logs show that the problem is that the shibd_default service isn't started you should look at using the ALWAYS_START_SERVICE property [1]
