PathTooLongException when running "Setup.bat" for the source build

Hey joe.ds-

Running Setup.bat creates and fills a number of folders that are rooted in the same file path where Setup.bat exists. The error that you’re seeing is due to the full file path from the drive root is too long. The easiest way to solve this is to move the folder that contains Setup.bat to a folder closer to the drive root and then run Setup.bat again.

Cheers
