...mmm...If it is the archerii_ph_kax2.zip from here on SimV then it is probably as Ash says....
The file is included in the download but depending on how you installed it, it could be missing from your Fs9 folder......the Readme file (did you read this?) includes this statement..
Quote:- "To prevent FS 2004 from crashing, the file GaugeSound.dll must be present either in the Flight Simulator 9 or in the Windows\system32 directory. Also, the file r_c_PA28stall.wav must be in the Flight Simulator 9\Sound directory. Both files are in this .zip and will be in place after unzipping it into the Flight Simulator 9 directory."
If you unzipped to your desktop which is a safer option and not directly to the Fs9 Folder...then you will probably have to put a copy in manually........Please read the installation readme though..........
..good luck...commoner
