I only have a file called msvcr70.dll in my system32 folder which I copied into my FSX folder as well.  I updated the C++ stuff as recommended in the Knowledge base and still don't have a msvcr71.dll as well as cycled through the views, reinstalled the aircraft, reloaded it as suggested and changed the .ini file and still don't have any of these sounds back.  No cabin crew announcements, no seat belt sounds, no APU and I don't know what else.  I do have the pilot's windows opening sound though...real useful that one ;D

Now what?  What is the difference between msvcr70.dll and msvcr71.dll?  Were can I get msvcr71.dll? :-?
