I am trying bcvtb for energyplus and matlab co-simulations but get error even with example file in matlab as

Error using loadlibrary (line 422) There was an error loading the library "bcvtb" The specified module could not be found.

Error in establishClientSocket (line 22) loadlibrary(BCVTBLIB, @bcvtb);

Error in simulateAndExit (line 39) sockfd = establishClientSocket('socket.cfg');

Caused by: Error using loaddefinedlibrary The specified module could not be found.

I check the version of C++ compiler is 2013 with Win 7.
