Based on the information you have provided I will assume that when you say IRST you are referring here to Intel® Rapid Start Technology and not the Intel® Rapid Storage Technology (which are different technologies).
At this point I am not totally sure of the components you have in your system but you can check the Rapid Start Technology guide here:
The message that says “This computer does not meet minimum requirements for installing this software" most of the times is because the software we have from our side is generic software for branded computers or OEM systems. I would recommend you trying to deleted the software from Programs and Feature under control panel and then try installing the one your computer manufacture provides.
