Thanks for finding this. I was able to find that the only thing that needed to be added was the "Add Xinput1_4.dll, XInput9_1_0.dll and XAudio2_8.dll" if you are running Server 2012 R2. I read up on a way to manually install those files, but would need to pull the files from a windows 7 computer. Probably something similar for the 2008 installation.
