I'm really confused by the 2 different editions of SQL Server 2012. There is RTM and SP1 which both seem like different code branches. How do I upgrade an RTM install to a SP1 install. I've tried upgrade and that doesn't let me choose the old RTM install.

Gary, the part of SQL Server setup you need to look at is as follows. Make sure you record what users and groups are in the Specify SQL Server administrators section.
I figured it out--portions of the install need .NET 3.5 which is not standard on Server 2012. To enable this on Server 2012, you need to put the 2012 disk in, and type the following command in the shell prompt:
dism /online /enable-feature /featurename:NetFX3 /all /Source:d:\sources\sxs /LimitAccess
Found the solution here. Also, reviewed the pre-reqs again at Microsoft's KB2681562.

But you ARE an admin, right?
No. it is the same like any SERVICE PACK. RTM is the released original, SP1 the first service pack. EXACTLY the same like XP, Windows 7 - not windows 8 where the SP is called 8.1. Same like exchange. Like any enterprise software.
Download the SP1 installer, run it.
Why not? Check version numbers. We need a lot more info. For example error info, or what it sees - there is a nice dialog telling you which windows versions you have installed.
