I had this same, look at Process Manager I bet cscript hang up your installation. I modficate my scripts and put older support files OffScrubsXX.vbs with date created 02-05-2014 (before I had a problem with new files with created date 12-2014).

I used for install Office 365 ProPlus ( works )

<#
.SYNOPSIS
This script performs the installation or uninstallation of an application(s).
.DESCRIPTION
The script is provided as a template to perform an install or uninstall of an application(s).
The script either performs an "Install" deployment type or an "Uninstall" deployment type.
The install deployment type is broken down in to 3 main sections/phases: Pre-Install, Install, and Post-Install.
The script dot-sources the AppDeployToolkitMain.ps1 script which contains the logic and functions required to install or uninstall an application.
To access the help section,
.EXAMPLE
Deploy-Application.ps1
.EXAMPLE
Deploy-Application.ps1 -DeploymentType "Silent"
.EXAMPLE
Deploy-Application.ps1 -AllowRebootPassThru -AllowDefer
.EXAMPLE
Deploy-Application.ps1 -Uninstall
.PARAMETER DeploymentType
The type of deployment to perform. [Default is "Install"]
.PARAMETER DeployMode
Specifies whether the installation should be run in Interactive, Silent or NonInteractive mode.
Interactive = Default mode
Silent = No dialogs
NonInteractive = Very silent, i.e. no blocking apps. Noninteractive mode is automatically set if an SCCM task sequence or session 0 is detected.
.PARAMETER AllowRebootPassThru
Allows the 3010 return code (requires restart) to be passed back to the parent process (e.g. SCCM) if detected from an installation.
If 3010 is passed back to SCCM a reboot prompt will be triggered.
