Installing Exchange 2010 SP3 on Windows 2012 (NOT R2)

There are plenty of easily found documents on how to do this, so I'm not going to repeat the instructions here. However, I ran into an issue that none of those articles mentioned, the details of which are below.

I had installed all of the various Exchange 2010 SP3 prerequisites on Windows Server 2012 and followed all of the articles exactly, but whenever I ran setup.exe (GUI) or setup.com (CLI) to install Exchange, I got the an error containing the following phrase:

Could not load file or assembly 'System.Management.Automation' or one of its dependencies.

If you encounter the error message, you simply need to use Server Management Console to install the Windows PowerShell 2.0 Engine feature.
