how do you determine what is causing a pre-requisite to fail?

how do you determine what is causing a pre-requisite to fail?

I've added logs for each pre-requisite and they appear to successfully install, but somehow my calling installer indicates that the pre-req failed to install.

I'm at loss in what to look for. Any ideas?

Reports of a prerequisite failing are typically caused by its conditions not changing after it is installed. Make sure that it looks for an artifact that the installation will update, be it a file, file version, or registry change. (This also happens if the prerequisite fails to install, of course.)

One thing you can do is run your setup.exe from the command line and pass it the switch /debuglog this logfile should output the prereq's and you might catch why it's failing.
