When you start FS 2004 each time, it will check versions of add-on *.dll (dynamic link library) files. If you repeatly see a warning screen at boot up of your Flight Sim, reporting an older file, and you're confident that it will work with FS 2004, you can open the fs2004.cfg file, then insert a new section called "OldModules".A common example of this will be the third party FSsound.dll file that many gauge programmers used for FS2000.
You can add this entry:
[OLDMODULES]
FSsound.dll=1
Setting this value to 0 won't load the module, but will still disable the warning screen. A value of 1 will load the module, again disabling the warning screen.
Remember: FSsound.dll must be loaded for the crew annoucements to work.
For WindowsXP users, the file can be found in folder:
C:\Documents and Settings\your_user_name\Application Data\Microsoft\FS9
If you cannot find this folder than it is hidden. In that case open
your Windows Control Panel, select Folder Options from the menu
Extra, select the View tab and in there you need to check the
option for "Show hidden files and folders".
For Windows98 users, the file can be found in folder:
C:\Windows\ApplicationData\Microsoft\FS9
For safety reasons, first rename the FS9.cfg file into FS9-org.cfg. This is for later use in case you want to revert to the original file.
Now open the file FS9-org.cfg with any text editor program and add the following two lines to the bottom of the text. Tip: use copy and paste to avoid mistakes.
