As with the RTM release of SharePoint 2013, Sharepoint 2013 SP1 has alot of prerequisites. This includes server features and additional EXE files that need to be installed before SharePoint will proceed with the install.

I created 2x scripts and 1x txt file, they are as follows:

Run both Scripts from Powershell.
