Assuming you're running NT4 or earlier or Win98 or earlier, start a
Command Prompt window (doesn't work from explorer), cd to your windows
system directory and "MOVE MFC42.DLL MFC42.DLL-OLD". This should be
possible. Then copy the new MFC42.DLL into there. New programs will
use it, but to get already running programs to use it you'll need to
reboot. Failing that you'll need to hack the RunOnce registry key to
get windows to do it for you on the next reboot.
If you select the mfc42.dll in explorer and press Alt-Enter, the
version tab will tell you which version of MFC you have installed. On
the microsoft support site (support.microsoft.com) there is a list of
shipped MFC versions - search for "MFC version history", or now there
is a dedicated page listing the shipped versions of *all* microsoft
components (and which product they shipped in), but I forget the exact
URL to this.
If you're running NT5/Windows 2000, then System File Protection
prevents this completely. The only officially endorsed way is to
update them through an official service pack or the windows update
website. (I'm sure other, less official, ways will be discovered very
soon though :-)
For situations like this, MS now recommend putting the needed version
of the DLL in the same directory as the application. I'm not sure if
this works 100% of the time now, but they've modified the way DLLs
work in Win2000 specifically to try and stop "DLL Hell".
