How to download rabbit field utility version 4.72 for MB200 controller?

I am trying to connect my controller MB200, with RFU version 2.45 but it is not detecting my controller.

From where and how can I download and install the
RFU 4.72 version?

RFU 4.72 is included in Dynamic C 10.72 and later.

I don’t recognize the product “MB200”, but RFU 4.72 should work with all Rabbit 2000, 3000, 4000, 5000 and 6000 products shipped by Zworld/Rabbit Semiconductor/Digi International.
