I'd forgotten all about this. First you need to install the base aircraft. I suggest you download the Fokker F27-200/500 Package (sf27.zip) posted on this page.
http://www.simviation.com/fs2004props18.htm This contains both the mk 200 and mk 500 versions.
Installation is straightforward. Extract the zipfile using the Right-click WinZip/Extract to Folder .... option. Open the extracted sf27 folder & paste the f27200 & f27500 folders inside it into FS9\Aircraft. To install the gauges paste the contents of the folder named gauges into FS9\Gauges. That's it. Check both versions of the aircraft out in FS9 to make sure they're installed properly.
Now for the repaints. I'll use the Air UK F27-200 posted at the bottom of this page as a example.
http://www.simviation.com/fs2004props81.htmDownload AirUKF27-200Late80s.zip & extract it as I described above. Open the AirUKF27-200Late80s folder you just extracted until you find a folder named texture.3. Paste the texture.3 folder into the f27200 folder you previously installed to FS9\Aircraft.
Now you need to edit Aircraft.cfg to recognise the new variation. Go back to the AirUKF27-200Late80s folder & open New Text Document.txt in Notepad. Select the sample CFG entry by dragging the mouse across the text & copy it. This is the entry.
[fltsim.XX]//insert next number
title=Fokker F27 Mk 200 Paint3
sim=f27200
model=
panel=
sound=
texture=3
panel_alias =
sound_alias =
kb_checklists=
kb_reference=
atc_id_color=0xffffffffff
atc_id=GBLGW
ui_manufacturer=Fokker
ui_type=F27 Mk 200
ui_variation=AirUK (Later livery)
description=Air UK F27 200 (Later livery).
atc_heavy=0
atc_airline=AirUk
atc_flight_number=
Now open Aircraft.cfg of the f27200 folder in Notepad. Paste the new entry below the last existing variation & just above the [General] header. Change the [fltsim.XX] entry to the next number in sequence. In this case it will be [fltsim.2]
It should now look like this. (The new entry is in red.)
[fltsim.0]
title=Fokker F27 Mk 200
sim=f27200

etc. etc
Finally exit Notepad saving changes when prompted. Now go & fly your Air UK F27-200. It will be listed on the menu as
AirUK (Later livery)Hope that worked for you.
