If you're running on Windows, and get an error message upon application startup reporting that a file called msvcp140.dll is missing, this means that you need to download and install the Microsoft Visual C++ Redistributable for Visual Studio 2015
. Be sure to download the 64 bit version (vc_redist.x64.exe).
After installing that, try running MC-4 Hack again. If you have problems, please report here!
