Re: Where is the November 2001 SDK redistributable MFC42.dll?

The redist folder for the SDK contains a readme.txt which says:
"Redistributables can be found online at

It's a dead link which gets redirected.
I thought about just building the release MFC42.dll from the MFC
source supplied with the SDK but technical note 33 suggests
redistributing the prebuilt retail version is preferable:
"Ideally you should not need to rebuild the DLLs and if you
redistribute your application with the prebuilt MFCxx.DLL provided
with the Visual C++ product, you will avoid a lot of problems for
yourself and your users."

Except of course I cannot find the 2001 SDK version of the prebuilt
retail MFC42.dll
The VC6 CD contains a redistributable retail MFC42.dll dated
(modified) 1998.
I thought about using this, but I did a comparison of the VC6 MFC
source and the 2001 SDK MFC source and I see various small updates to
the MFC source. In light of that I am not entirely sure distributing
the VC6 MFC version is a good idea.
If you are wondering why, the reason I want to redistribute an older
MFC version is that later versions of MFC (2003 SDK onwards) have
changes which break me (fault of the program, not MFC). I am unable to
update the program but to keep it going I just want to redistribute
(into the product bin folder of course, not into the system) the
version of the MFC42 dll that the program was written for
If anyone has any suggestions about where to find the November 2001
SDK version of MFC42.dll, or has info about whether I can just use the
VC6 CD retail MFC42.dll version, that would be brilliant.
Sorry for such an out of the blue question, Thanks.
James:
I guess I am confused. The platform SDK and the MFC/CRT DLL's are completely
separate beasts.
Each version of the VC compiler (4, 4.2, 5, 6, 7, 7.1 ...) and each service pack
thereof has a new version of the MFC/CRT DLL's. For VC6 (and back to VC 4.2) the
names of these DLL's did not change with the VC version or service pack, and
were supposed to be backward compatible. Anyway, you should always distribute
the MFC/CRT DLL's that came with your version of the compiler. If you are using
VC6, and you have not applied any service pack, then the DLL's on the VC6 CD
should be the correct ones. (Of course you should not replace later versions in
the System folder.)
As to the Platform SDK, if you are using VC6, you should be able to use any
version up to February 2003 (later versions were not compatible with VC6). The
platform SDK corresponds to the version of the OS that it was written for.
I'm really not sure what your question is.
Also, why can you not update your program to a later version of the compiler
(and its MFC)? The breaking changes in MFC were pretty minimal.
