Coogee you are headed in the right direction. If you don't get any joy unzipping into the gauges folder try
opening the folder until you can access the individual files. Do that in a temporary folder. Once you have access to the individual files copy them one by one into theFS2002\Gauges folder. You may find that you are copying onto an existing file and are asked if you wish to overwrite. DO NOT. In all those files you may find only one or two that do not come up with an overwrite
command THOSE are the ones you copy to \Gauges.
Pain in the backside you bet. Works for me! Only way!
Now to see Barry Blaisdell about his panels.

White on White fly all night.
Red on White you're alright.
Red on Red you'll soon be dead.
