Having some difficulty getting started with BGEE

Basic game runs fine.

I want to start adding fixes, tweaks, mods, npc's a little at a time.

So, here I am trying to install the latest version of NPC Project, i.e., bg1npc-v23.3.exe

I'm getting the fatal error message that I need to install into the Infinity game engine folder.

I'm installing bg1npc-v23.3.exe into what I THINK is the game folder but I must be wrong about something. I tried to add some screen shots to show you what folder I am installing but I guess there's no way to do that here.

Any thoughts? Once I get going I'll be fine. I modded Tutu big time and don't remember having this issue.

I realize this is very basic... but I'm a basic kind of guy. CT
