I've created two new .prq files and they seem to be getting inserted into my MSI project. However, when I run the install it is ignoring my command line switches and using all defaults. Is there a way to log the steps where the command is issued so I can see what switches are being set? Is there a way to look into the setup.exe and see if the new .prq's are actually there? Any other thoughts?
You can run your setup with the /debuglog parameter and it will spit out a lot of potentially useful information about prerequisites and other steps it takes. One thing that comes to mind is that both the regular and silent command line should be filled in if you need to pass special parameters to your prerequisite.
I found the problem. I created my new .prq by copying another and editing it. I failed to clear the alternate .prq download site for web download of prerequisites. The default .prq was being downloaded and used instead of my new one.
