I'm attempting to build out our Lab Manager with TFS 2012. On a virtual machine running Server 2003 SP2 32bit, I'm attempting to install the Visual Studio Agents 2012 and am running into an error:

Setup Failed!
Install cannot continue because some required components failed. 
Microsoft .NET Framework 4.5
Asia

Looking into it, the install log is erroring when it's attempting to install dotNetFx45_Full_x86_x64.exe component. Looking at that install log, it is failing with:

The .NET Framework 4.5 is not supported on this operating system.

So, I see according to the Agents 2012 MSDN documentation, that Server 2003 SP2 is supported by Agents 2012. But I also see that according to the .NET 4.5 MSDN documentation, Server 2003 isn't supported.

So how do I install Agents 2012 on 2003 SP2 as the documentation implies I can?
