Unresolved symbols in MSVCRT.DLL when running a py2exe packaged program.

[Tom]

I disagree.

You can distribute system dll's.  You are expected to, and sometimes you
have to.  You must insure that the version you load is at least equal to the
version that you linked against.

I have done this (distribute system DLL's) on all windows except WinME and
the 16bit ones.  Unfortunately I can't say how I did it precisely, because I
just used InstallShield.  But I believe that, where SFP exists, you must use
specific and new API's to replace DLL's, otherwise the system will back out
your changes.

One solution is to specify the changes in an .INF file and let the system
worry about these details (but this has its limitations).

I assume that Python itself updates the MSVCRT.dll.  Might look at how it
does it on Win2K.

One way I remember getting the error being described was writing code for
the install process that used the CRT and that got executed before my
version of the CRT got installed.
