gfxUI.exe is stopped working

Issue when running Windows Server 2008 r2 (x64) on Intel Motherboard, with both .net 4 as well as 3.5 installed.

Description:
Stopped working
Problem Signature:

The following worked for me it seems that the Intel driver requires .net 3.5 to be enabled on the server.

In Server Manager > Features > Add Features

In the list of features to install on this server, select .NET Framework 3.5.1 Features

I would then recommend a reboot once it has installed.
