Office 365: Office 2016 Installation from USBKey using relative path

[30/04/17] Update: Following this post, I’ve pushed this script to Github if you want to contribute.

I was trying to use Office Deployment Tool (ODT) using the relative path for our Office 2016 ProPlus deployment (On USB Key & Hard Drive).

As USB Keys are mounted each time with different letters depending on how many devices already mounted. I was stuck cause ODT XML Configuration file does not support the relative path.

You can see this limitation on this page: here

To run this script on client computers, I’m using this simple launch cmd.

powershell.exe -ExecutionPolicy bypass -File .\path\install.ps1

The idea was to read and replace the line with SourcePath="Path" with the current dir. Quick and Dirty.

# Installation Office 2016 from USB Key
# VGR - 09/03/17

# Current folder of the running .ps1 file
$PS1dir = [System.IO.Path]::GetDirectoryName($myInvocation.MyCommand.Definition)

# Path of the configuration
$conf = "$($PS1dir)\conf_FR.xml"

# Current path with reformated end of XML line
$PS1dirEOL = "$($PS1dir)`">"

# Replace old line with the current folder
(Get-Content $conf) -replace '<Add OfficeClientEdition=.*', ('<Add OfficeClientEdition="32" Channel="FirstReleaseDeferred" SourcePath="'+$PS1dirEOL) | Set-Content $conf

# Running Office 2016 installation from new configuration file
$exec = "$($PS1dir)\setup.exe"
& $exec /configure $conf

That’s all folks!
