3. Windows C++ Redistributables

It is a good practice to have the latest C++ redistributables on your Windows system. 

You can download and install the official release of Microsoft from https://aka.ms/vs/17/release/vc_redist.x64.exe 

If you experience a crash of the MP Host on Windows, this most probably is due to an incompatible version of C++ redistributable installed. Install the above version (which is a permanent link to the latest release) and it should fix the issue.
