How to Upgrade SEPM to version 12.1.2

I need some instruction on how to upgrade the SEPM (version 12.1.650) to version 12.1.2015.  I went to file connect to download the file.  I unzipped the file and ran the excecutable on a test server.

When the wizard started - i noticed that i didn't get the usual first page that lets you either install the Admin console or install the client.  It just does the client install and finishes.  How do I upgrade the actual SEPM?  or does the SEPM version stay the same and there is just a newer version package to assign to groups?
