I'm coming back to FS due to life circumstances that kept me away. I am having difficulty remembering whether I actually need to move the GuageSound.dll file from each download to the main Flight Simulator folder (FS 2004). Or if that is a one time deal. I'd hate to be putting multiple files with the same name, if it is necessary can I rename it?
Maybe what he wrote here will help.
That indeed did help, it appears I only need it the one time.
Great! Now enjoy flying again.
