How to change the path of DebuggerInterface.dll?

I was interested in debuggerinterface to look at the page below.

UnrealScript Debugger Interface
https://udn.epicgames.com/Three/DebuggerInterface.html

I created a DebuggerInterface.dll, placed in the same folder as the exe.
When I start the exe, there was a reaction to DebuggerInterface.dll.

However, I want to change the path of DebuggerInterface.dll.
When reading the description, it is to be able to change by Debugger.ini.
However, this Debugger.ini do not know well.

Where should I put the Debugger.ini?
Is it to what description to Debugger.ini?
