This is how I did it nothing fancy. Used java -jar install.jar to install Kojo on a test machine then copied installation directory to network share.
On SCCM created a script application and used the following powershell script.

## Install Kojo 2.1 for All Users Script 20140815 Chris Jensen
##
## Tested on Windows 8 (x64)
##
## The script is designed for Microsoft System Center Configuration Manager
## Create an application and execute -> powershell.exe -executionpolicy bypass -file InstallKojo.ps1
##
## Script not implementing any error handling

## Create Kojo2 folder and copy Kojo2 from the SCCM Package to the new folder
if (!(Test-Path -path "$env:ProgramFiles\Kojo2" -pathType Container)) {New-Item "$env:ProgramFiles\Kojo2" -ItemType Directory}

$MyPath = Split-Path $MyInvocation.MyCommand.Definition

if ((Test-Path -path "$env:ProgramFiles\Kojo2" -pathType Container)) {Copy-Item "$MyPath\Kojo2*" "$env:ProgramFiles" -force -recurse -verbose}

## Create Kojo2 folder under the start menu
if (!(Test-Path -path "$env:ALLUSERSPROFILE\Microsoft\Windows\Start Menu\Programs\Kojo v2" -pathType Container)) {New-Item "$env:ALLUSERSPROFILE\Microsoft\Windows\Start Menu\Programs\Kojo v2" -ItemType Directory}

## Create Kojo Shortcut for all users
$ws = New-Object -com WScript.Shell
$Sc1 = $ws.CreateShortcut((Join-Path -Path $env:ALLUSERSPROFILE -ChildPath "\Microsoft\Windows\Start Menu\Programs\Kojo v2\Kojo-Desktop.lnk"))
$Sc1.TargetPath = $env:ProgramFiles + "\Kojo2\bin\kojo.exe"
$Sc1.Description = "The Kojo Learning Environment"
$Sc1.Save()
$Sc2 = $ws.CreateShortcut((Join-Path -Path $env:ALLUSERSPROFILE -ChildPath "\Microsoft\Windows\Start Menu\Programs\Kojo v2\Kojo-Web.lnk"))
$Sc2.TargetPath = $env:ProgramFiles + "\Kojo2\bin\webkojo.cmd"
$Sc2.IconLocation = "%programfiles%\Kojo2\bin\kojo.exe, 0"
$Sc2.Description = "The Kojo Learning Environment via Webstart"
$Sc2.Save()

## Always assume success
Exit 0

And to uninstall

## Remove/Uninstall Kojo2 Script 20140815 Chris Jensen
##
##
##
##
##
##

## Remove Spotify Program Folder
if ((Test-Path -path "$env:ProgramFiles\Kojo2" -pathType Container)) {Remove-Item "$env:ProgramFiles\Kojo2" -Force -Recurse}

## Remove Spotify Program Shortcut
if ((Test-Path -path "$env:ALLUSERSPROFILE\Microsoft\Windows\Start Menu\Programs\Kojo v2" -pathType Container)) {Remove-Item "$env:ALLUSERSPROFILE\Microsoft\Windows\Start Menu\Programs\Kojo v2" -Force -Recurse}

##Always Assume Success
Exit 0

I'm sure this could be improved in many ways and perhaps made more efficient but it does what it's supposed to.

Would you mind sharing your script so that others in a similar situation can benefit from your solution?

It worked.

Good to know.

It's to be used on multiple computers in a classroom for teacher education.

Interesting. May I ask, where?

I installed Kojo on a test machine like you suggested and copied the files to a network share, used SCCM and a powershell script to copy the installed files and create shortcuts.

if it works I'm happy to go with that solution.

It should work.

I have not tried the unattended IzPack install myself. Will play with it soon and post here if I get it to work.

Are you trying this out in a setting with multiple machines? A school? Would be good to know.

• Use the jar installer to install Kojo on a machine - into, say, ~/Kojo2
• zip up the Kojo2 dir (into, say, Kojo2.zip)
• Now, to do a silent install on a new machine, just unzip Kojo2.zip on that machine.

Or, you can try an unattended IzPack install:

I'm looking to perform an unattended installation of Kojo is this possible?
I've tried 'java -jar install.jar -options install.properties', but aside from INSTALL_PATH I have no clue as to what I'm supposed to enter in the properties file, if this is even an option.
