Okay.

When I add this one, I change these first lines:

[fltsim.XX]                           <-------- REPLACE XX FOR LAST NUMBER +1
title=CS 777-200 Captain PaintX       <-------- REPLACE X FOR LAST NUMBER +1

to

[fltsim.8]                           <-------- REPLACE XX FOR LAST NUMBER +1
title=CS 777-200 Captain Paint8       <-------- REPLACE X FOR LAST NUMBER +1

And then there is a very obvious difference that is caused by the fact that it was created for the Captain Sim 777 Exterior Model (version 0.1), as explained in the "description" here: description="777-200ER ZK-OKA REPAINT BY MARCELO F. VENEZIALE  Exterior Model\n777 Captain 0.1\n(c) 2011 Captain Sim www.captainsim.com"

So to fix it, I had to do this:

[fltsim.8]
title=CS 777-200 Captain Paint8     <--- I changed this to CS 777-200ER GE Captain Paint8
sim=x772      <--- I changed this to csx772_GE
model=200     <--- I changed this to 200ER_GE
panel=
sound=
texture=ANZ      
kb_checklists=
kb_reference=
atc_id=ZK-OKA
atc_airline=Air New  Zealand
atc_flight_number=777
atc_heavy=1
ui_manufacturer=Boeing
ui_type="777-200"     <--- I changed this to "777-200ER GE"
ui_variation=AIR NEW ZEALAND
ui_typerole="Commercial Airliner"
ui_createdby="Captain Sim"
engine_type=GE90-94B    <--- I had to add the entire line as it is not included in the fltsim.xx section in the readme file.
description="777-200ER ZK-OKA REPAINT BY MARCELO F. VENEZIALE  Exterior Model\n777 Captain 0.1\n(c) 2011 Captain Sim www.captainsim.com"

I also changed the description to this:
"777-200ER GE ZK-OKA REPAINT BY MARCELO F. VENEZIALE\n777 Captain 1.4\n(c) 2014 Captain Sim www.captainsim.com"

And here it is in Prepar3D v2.3 Academic:

Looking nice and pretty. ;)

And to make it all nice and easy for you, copy the following code, and you will only need to to change the first two lines to fix it in your aircraft.cfg file. ;)


Code (]
[fltsim.XX):

//<-------- REPLACE XX FOR LAST NUMBER +1 title=CS 777-200ER GE Captain PaintX       //<-------- REPLACE X FOR LAST NUMBER +1 sim=csx772_GE model=200ER_GE panel= sound= texture=ANZ       kb_checklists= kb_reference= atc_id=ZK-OKA atc_airline=Air New  Zealand atc_flight_number=777 atc_heavy=1 ui_manufacturer=Boeing ui_type="777-200ER GE" ui_variation=AIR NEW ZEALAND ui_typerole="Commercial Airliner" ui_createdby="Captain Sim" engine_type=GE90-94B description="777-200ER GE ZK-OKA REPAINT BY MARCELO F.

Enjoy.
