Hello John,
Welcome to the forum.
I am going to take a stab at this, but it will not be precise because the computer I am using does not have MCS installed so I am working straight from a rather poor memory:
At the top of Microcode Studio there are some words like File Edit . . . click on one of them, edit I think, anyway heck look into all of them, there you will find the options menues for the compiler, and the programmer, when you find the programmer options you need to give it a path statement to your programmer's executable file. Something like c:\Program Files\ICPROG.exe
Sorry I could not be more precise. Hope this helps.
