You may safely skip this step if you already have Microsoft Visual Studio 2017 Community or any other version of Microsoft Visual Studio installed.
This is one of the easiest actions described in this book. Go to https://www.visualstudio.com/downloads/ and download and run the installer for Visual Studio 2017 Community.
The installer has many options that you may want to select depending on your development needs; however, there is one that we need for Assembly development, and it is called Desktop development with C++.
If you insist on using the command line to build your Assembly programs, you can find MASM executables at the following locations:
VS_2017_install_dirVCinamd64_x86ml.exe
VS_2017_install_dirVCinamd64ml64.exe
VS_2017_install_dirVCinml.exe
