GitHub Setup Error when Building Engine

I’m attempting to install UE 4.16.3 to work on a source code that uses this version. I’m following this tutorial to clone the source code so I can choose a previous version: A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums. However, when I get to the “Build the Engine” section and attempt to “Locate the GenerateProjectFiles.bat file and double-click on it to run it.” I get the error attached.

I have Visual Studio Pro in this location: D:\Program Files (x86)\Microsoft Visual Studio\2017\Professional

Any Suggestions? Thank you!
