[Free][Windows only] UE4Duino 2 - Arduino (COM port) communication

Hi guys… I’m an arduino pro, but a UE noob. I downloaded the current version of UE 4.19.2, I created a ‘Plugins’ folder within my project and drop the contents of the github project there. When starting UE, it complains about missing or out of date binaries. could it be my folder structure? or is 4.19.2 not supported?

my path is:
C:\Program Files\Epic Games\UE_4.19\MyProject\Plugins\UE4Duino
