OK heres how you go about it step by step.
1. Download the file.
2. It will be a .zip file, so right click it, press explore.
3. Go in and when you reach a folder named panel.(whatever it is) click it and press Ctrl+C. (This folder should not have any more folders in it.)
4. Open your FS9 folder. Go to Aircraft, the open the folder of the one you want the panel installed into.
5. Press Ctrl+V. The folder should appear.
6. Open the Aircraft.cfg file in notepad etc. and where in the first paragraph it says "panel=" write after it what is after the dot on the panel folder. ie: if the panel folder was named "panel.a300" in the aircraft.cfg it should read "panel=a300"about 8 lines down the page.
7. Just to check it's worked, open FS and try it.
There is one exception to the tutorial above: the gauges are different. If theis is the case, in the .zip you downloaded there will be a gauge file. All you need to do s Copy (Ctrl+C) and Paste (Ctrl+V) into the FS9-->Gauges folder. In the highly (No, i really mean it) unlikely event this doesn't work, you must have deleted a gauge that was aliased.
Glad to be of service.
