Attempt to install software results in user32.dll error message.

[SteveS60]

I apparently made an unknown error. Now when I attempt to install two
software packages I receive error messages. One package results in the
message "The procedure entry point CallWindowProMF could not be located in
the dynamic link library user32.dll. Attempting to install the other package
results in exactly the same error message, but the procedure entry point is
DefWindowProMF.

In Safe Mode I renamed user32.dll, then attempted to install a copy of the
file from another computer. I still get the same error messages.

I can not find either procedure entry point when I search the registry.

My OS is XP Pro, Version 2002, Service Pack 2.

Help, or at least guide me to a more appropriate discussion group.

Are these install packages you wrote or are they packages you got from
someone else? The calls don't appear to really be part of user32.dll.

The only google link for either name (CallWindowProMF, DefWindowProMF), is
worth reviewing, but it doesn't look like the problem was solved there either:

Well those funtions don't exist in user32.dll, so the program is
crashing. It's badly written.

Maybe they meant to use CallWindowProc/DefWindowProc?

Their QA *really* sucks.
