Getting MXTools working for MX V8i SS3

Question

I have installed V8i SS3 (8.11.09.494), the AU release. Under add-ins menu there is an entry for infraTools. Selecting that menu option results in a dialog instructing download and install from Select Services. See attached image. 
 Traditionally this means downloading MXTools. However the latest I could find is mxt081107494en. . That version of MXTools is already installed on a parallel MX V8iSS2 install and only offers to change, repair or remove. 
 How can I install MXTools/infraTools for SS3?

During those 8 months or so only updated MX v8i SS3 releases were provided, the MXTools for SS3 wasn't updated and is still the same release. 
 While MX v8i SS3 supports a side by side install of MX v8i SS2 on the same machine the same isn't true for MXTools and the user has to decide what version of MX they want MXTools installed on.

If you don't have an install of MX v8 SS2 installed alongside MX v8i SS3 you will need to make the change in the wiki article below to get the input file runner to work correctly.
