Each time you log in to your computer the GSD Workspaces applications opens up. If not, it is on your desktop and says... GSD Workspaces and has the GSD logo and a red square around it.
Please use that to install any missing applications that you may need. If the software you are missing is NOT in the GSD Workspace, it can be added as requested.
To install the Unplug'd app. be sure to install it AND move it.
