Issue

When following the “Install Lab Environment” instructions for a training course, nothing happens when you run the command vagrant up.

The command line exits without any output or error, or just hangs.

Environment

Install PowerShell 3.0+, since this issue occurs when using PowerShell version 2.x and lower
PowerShell 3.0 is part of the Windows Management Framework 5.1, which you can download from: https://www.microsoft.com/en-us/download/details.aspx?id=54616
Reference (from the Vagrant official bug tracker): https://github.com/hashicorp/vagrant/issues/8783
Please note that this training is not officially supported on Windows 7, as stated on the requirements of “Install Lab Environment”
