System Center Installer - OMServer.msi returned error 1603

Having problems installing your secondary management server, maybe even your primary? Great post about pre-requisites. Setting up our secondary server, the management server installer was failing. I had made sure to install the report viewer modules, .NET 4.0 but forgot .NET 3.51. The installer won't tell you directly that the prerequisite was missing and will simply fail, leaving you to pour through a large install log to find the problem.

If you're seeing this in your install log, it may be the same case:

Always: :LaunchMSI: Setting rollback to true
[16:58:55]: Error: :LaunchMSI: MSI C:\SCOMSP1\Setup\AMD64\Server\OMServer.msi returned error 1603
