.SYNOPSIS
This script installs the current Citrix WorkspaceApp on a MCS/PVS master server/client or wherever you want.
		
.Description
Use the Software Updater script first, to check if a new version is available! After that use the Software Installer script. If you select this software
package it gets installed. 
The script compares the software version and will install or update the software. A log file will be created in the 'Install Logs' folder. 

.EXAMPLE

.NOTES
Always call this script with the Software Installer script!
