I have six "MFC42.DLL" files. This file causes Eudora (my e-mail
program) to crash,Therefore I want to delete all of the files. If not,
should I keep the one in SysIni? If not, where?

Thank you,

mfc42.dll is almost certainly a necessary file (microsoft foundation
classes v. 4.2)... where ever you find it it's probably being used by
something...

i'm not sure how you've determined that this file is causing errors for
eudora, but if eudora is using it, deleting it isn't going to make
things better, it's most likely going to make them worse... perhaps the
copy that eudora is using is corrupt, or perhaps some other file in
eudora is corrupt... have you tried reinstalling eudora?

Looong time ago, there were problems w/ MFC40.DLL (forty). Some
app's were overwriting "good" ver's with some old beta ver's.
This might not causing your problems but it might be worth to
search the MS KB.

What OS are you running? I have 4 copies of MFC42.DLL on
this system.

Here's the versions that I have:

6.00.8447.0
6.00.8665.0

Right click on the files then click on Properties. The
second tab will display the file version and info.

Disregard the file date because they get changed around a
lot by various installation programs.

Check this site for more info on these files.

http://support.microsoft.com/default.aspx?scid=http://
support.microsoft.com%2fservicedesks%2ffileversion%2fdllinfo
..asp&fp=1

The latest versions are 6.5.3014.0 and 6.0.9586.0

I've seen recommendations to remove the extraneous copies of
..DLLs and only have one copy in the C:\Windows\System or
C:\Windows\System32 folder because Windows searches the
system for needed files when a program is launched and
having different versions can cause conflicts.

I've also seen recommendations to pick the newest version of
the file and copy it to all of the locations that it
appears.

Then again I've seen cases where a program may not work
properly with an incompatible version .DLL!

Crappy code writing by programmers including those at
Microsloth!

If you make and version changes, be sure to rename the old
files 1st so that you can easily go back to those versions
if needed.

YMMV

I know this probably won't make you feel any better, but, I have seen quite
a few people in other groups and forums with the same or similar complaint
that involves the MFC42.DLL. A good many of them also use Eudora.
Hopefully, the information here will help resolve your problem.
