UNINSTALL AND RESTORE:

Assuming your FS9 install is in the default location of:

C:\Program Files\Microsoft Games\Flight Simulator 9


....select which light set you wish to restore from this folder then double click the file. When the WinZip Self extractor box appears simply click the "UNZIP" button. The selected lights will then be restored.

IMPORTANT!!!
If your FS9 install is NOT in the default location, DO NOT click the unzip button. Instead, click the BROWSE button and browse the WinZip self extractor to your main Flight Simulator (Flight Simulator 9) install directory. Once the WinZip self extractor is browsed to the correct location (Flight Simulator 9), then click the "UNZIP" button.


PLEASE NOTE:
Both Project Opensky and PMDG use a combination of their own lights AND default Flight Simulator lights. In order to restore the lights for Project Opensky and/or PMDG to a 100% original state you must also restore the default Flight Simulator Aircraft lights as well (FS Aircraft Lights Restore.exe).
