Windows Installation - Go Programming
- Use the MSI file and follow the prompts to install the Go tools. By default, the installer uses the Go distribution in c:\Go. The installer should set the c:\Go\bin directory in window's PATH environment variable. Restart any open command prompts for the change to take effect.
