In the bin32 and bin64 directories of your MWLL installation (Crysis Wars\Mods\MWLL) are Visual C++ redistributable packages that need to be installed for MWLL to run. When installing the mod, there should've been a prompt to install them that you can skip, even though it tells you not to unless you're absolutely sure you already have them. The files are name vcredist_x86_2005_KB2538242.exe for the 32-bit version, and vcredist_x64_2005_KB2538242.exe for the 64-bit version. If you have a 32-bit OS, you only need the x86 one, and if you have a 64-bit OS, just install both so you can run both versions of the game.
