End users must have the Horizon FLEX Client software installed on their local computers before they can download the Horizon FLEX virtual machines. Supported clients included in the Horizon FLEX package are Fusion Pro for Mac OS X machines and Workstation Player for Windows machines.

You can create a mass deployment to install the Horizon FLEX Client on many systems at one time, or you can instruct end users to obtain the Horizon FLEX Client from the VMware Web site and install it themselves. You can also run an unattended Workstation Player installation on multiple Windows machines.
