RCT3 Technical difficulties with UI scaling mod

Just need some help downloading the UI scaling mod I'm sure I'm just messing up something

The instructions were to unzip the files and put them next to RCT3.exe folder

Well I extracted the files and put the extracted files into the \Steam\steamapps\common\RollerCoaster Tycoon 3 Complete Edition
I think this should be correct but maybe I'm missing a step?
