Dear David,

I never used Cplex on Windows with the VS compiler but it should
(hopefully) work out of the box. What kind of errors do you get? Can you
send me / us the console output?
> Can MinGW, which compiles and links code to be run on Win32 platforms, actually be used for that purpose?
I don't fully understand what you mean. You want to use MSVC to compile
and link your code, right? In my previous mail, I just explained how to
call the VS compiler directly when using msys. Actually, this has not
much to do with MinGW. Or do you want to use MinGWs gcc compiler? Of
course, this would be an alternative to MSVC.
> When compiling SCIP, it asks for "soft-links" to CPLEX. How should it look like in case of CPLEX (64-bit) on windows (there is only a cplexXXXX.lib file)?
In MSVC you need to use *.lib files when linking to other software. I
guess, in the end you just need to copy the CPLEX library to
scip/lib/libcplex.lib. By the way, is this a static CPLEX library or
just the linker library for the Windows dll?

Benjamin
