.SYNOPSIS
    This script installs VMware Tools and VMware/Omnissa Horizon Agent on a virtual machine.
    It checks if the machine is a VMware virtual machine, downloads the latest VMware Tools installer,
    and installs it silently. It also installs the VMware/Omnissa Horizon Agent from a specified path.
