I placed everything that was in the rar file in:
C:\Program Files\Black Isle\BGII - SoA
With all the other tutu enhancement mods I have installed, I installed them into that directory and then I just clicked on the exe, and they installed fine.
The contents of the rar file was:
Setup-FinchNPC.exe
Setup-FinchNPC.TP2
The directory contents are:

I have also tried extracting the files into the folder FinchNPC and FinchNPC v1_2 and clicking on the exe in the main directory to see if that would work, but the result has been the same. If you attempt to click on the one in the folders in that setup, you get a "cannot find dialogue.tlk" error.
If someone could list the relevant directory contents of a working version, maybe I could try to duplicate it.
