The following sections provide instructions on installing ADCME on Windows computers.

Detailed instructions to install Julia on Windows

For Windows users, you can press the Windows button or click the Windows icon (usually located in the lower left of your screen) and type julia. Open the Desktop App Julia and you will see a Julia prompt.

## Install C/C++ Compilers

To use and build custom operators, you need a C/C++ compiler that is compatible with the TensorFlow backend. The prebuilt TensorFlow shipped with ADCME was built using Microsoft Visual Studio 2017 15. Therefore, you need to install this specific version.

1. Double click the installer that you just downloaded. You will see the following image:

A free community version is available (Visual Studio Community 2017). Click install and a window will pop up.
