Hi,
MMEX got rid of hand-made solution for Visual Studio 2008 Express. The mmex\mmex.sln and *.vcproj files have removed. Bakefile generates solution for us. Read instructions how to build into mmex\build\msw\readme.txt.

Do not modify solution's files, all changes will be lost after running mmex\bakefile.bat. If you need something to change, modify bakefiles in mmex\build\bakefiles.

Full switching to bakefile simplifies support of all build configurations and enables to use compilers from different vendors and different versions of the same compiler. For example, now you can build MMEX using Visual Studio 2003 or later, MinGW and Borland C++ (I did not check Borland yet).
