Agenda
• Topics● Part I: The Art of Software Packaging● Part II: The Science of Software
Deployment
Many IT Professionals have problems with automated software distribution because it feels like a complicated topic.
But there are really two halves:Software Packaging
…and…Software Deployment
In this session, you’ll learn the nuances of both.
Automated Software Deployment
• There are two halves to rapidly and remotely installing applications:
• Repackaging – A software installation must first be reconfigured to install without prompting the user or requiring additional information.
• Deployment – The repackaged software installation is then loaded into a deployment tool and scheduled for deployment.
Part IThe Art of Software Packaging

Repackaging
• Consider the typical installation…• Insert the CD/DVD media• Double-click setup.exe or setup.msi• Next…Next…Finish…• Head to the next desktop
Repackaging
• Consider the typical installation…• Insert the CD/DVD media• Double-click setup.exe or setup.msi• Next…Next…Finish…• Head to the next desktop
• In order to deploy the same software automatically and remotely, you must…• Figure out how to complete the software installation
without requiring input by the user.• Figure out how to execute the reconfigured setup.exe
or setup.msi file locally on designated desktops.
Repackaging
• Software installations arrive in one of essentially three formats.• .EXE-based setup files
• Most often today, EXEs actually wrap around an MSI• .MSI-based setup files
• These are slowly becoming the primary mechanism for Windows software installations
• Copy-it-yourself formats
• These are relatively rare these days.

• Copy-it-yourself formats
• These are relatively rare these days.
• Of the first two above, virtually all are packaged using one of the major packaging utilities:
• Wise Package Studio• InstallShield• Inno Setup• Nullsoft Scriptable Install System
Repackaging
• Each format and packager has its own characteristics and switches.
• Adobe Acrobat: AcroRd32.exe /s /v/qn• Installation switches define the “hidden” parameters that can be
used to install the package.• Silent switches instruct the package to install without prompting
for input.• Some have neither. Some have nothing.

• Thus, while every software installation is different, they are in many ways the same.
• You need to sleuth out if switches exist and what they are!• Or…(More on that in a minute!)
Repackaging – MSI’s
• MSI installation uses the native Microsoft Installer• Microsoft Installer is the framework built into Windows.• Like Microsoft Update, but for installing software.• “Silent” switches are common across all installations.
Repackaging – MSI’s
• MSI installation uses the native Microsoft Installer• Microsoft Installer is the framework built into Windows.• Like Microsoft Update, but for installing software.• “Silent” switches are common across all installations.
• Packaging tools automatically interrogate the MSI database to determine silent switches & customizations.
• Customization and silencing is done at command-line.• msiexec /i /qb- AppA.msi DESKTOP_SHORTCUTS=0• msiexec /i AppB.msi TRANSFORMS=custom.mst
MSI Examples
• The standard command syntax for any MSI is…• msiexec.exe – Invokes the installer, and then…
• /i – Install
• /a – administrative install
• /l* – Log all information
• /q – No user interface
• /qb- – Basic user interface with no dialog boxes
• PROPERTYNAME = PropertyValue
• msiexec /qb- /l* logfile.txt /i setup.msi NAME=Value

Repackaging – EXE’s
• EXE files have no common switch schema.• There’s no central authority that governs EXE switches.• Depending on the packager used to create the EXE, there are
some known tricks.
• Finding the correct “silent switches” is key to installing properly. And they can be anything!
• AppA.exe /s /v/qn• AppB.exe /quiet /norestart• AppC.exe /go /blowyournose• AppD.exe /take /mywife:please
Don’t reinvent the wheel. Reference the Intertubes for applications and their silent switches.
www.AppDeploy.com
EXE Examples
• InstallShield (Ol’ school)● Run the installer with the /r switch on a reference machine● Proceed through the dialogs, answering prompts as you would
on the client machine● Complete the installation● The installation will create a setup.iss file in %windows%● Use this file to run the installation● setup.exe /s /f1setup.iss [/f2logfile.txt]
• InstallShield (Nu’ school, with Wrapped MSI)● Setup.exe /s /v/qb● Characters after /v are passed to the wrapped MSI file.
• Wise Package Studio, Others…● setup.exe /s
EXE Examples
• Also Try…● /a● /q:a /r:n● /silent● /passive● /quiet● /norestart● /?● /help
• /? and /help sometimes pop up a dialog box that contains useful clues.
EXE Examples
• Many EXEs these days are actually MSI wrappers● This means the EXE does little more than launch an MSI
installation● fileName /s /v/qn – Anything after the /v is passed to the
wrapped MSI file
EXE Examples
• Many EXEs these days are actually MSI wrappers● This means the EXE does little more than launch an MSI
installation● fileName /s /v/qn – Anything after the /v is passed to the
wrapped MSI file
• Trick #1: Use the /a switch to perform an “administrative install”, which sometimes will unpack that MSI.

• Trick #1: Use the /a switch to perform an “administrative install”, which sometimes will unpack that MSI.
• Trick #2: Start the EXE installation, but don’t finish it!● Double-click the EXE.● Wait for it to unpack.● When the first prompt appears, check %temp% for unpacked
MSI install files.
• It all depends on who wrote the installer…

Repackaging – Diff’s
• Some software is exceedingly complicated, doesn’t include “silent switches”, or simply won’t install with the other two mechanisms.
• For these, we run a “diff”, yo.
Repackaging – Diff’s
• Some software is exceedingly complicated, doesn’t include “silent switches”, or simply won’t install with the other two mechanisms.
• For these, we run a “diff”, yo.
• The process to do this…• Build a barebones desktop of the same OS/SP. Virtual
machines make this easy.• Snapshot its initial configuration.• Install and configure the application.• Re-Snapshot again.• Run the packager’s “diff” tool to log and subsequently package
the file/driver/registry changes.
• In some cases this can be easier than an EXE install.
Repackaging – Diff’s
• SLIGHT PROBLEM: Most packagers that can do this are expensive, natch.
• Caphyon Advanced Installer• WinINSTALL MSI Packager• Wise for Windows Installer• EMCO MSI Package Builder• Acresso AdminStudio• Acresso InstallShield
• But there are some freeware alternatives…• Some of the above’s “free” versions• AppDeploy Repackager• SMSInstaller• WinINSTALL LE
We’ll use WinINSTALL LE in a sec…

Post-Installation Customization
• NEXT STOP: Customizing that app after its installed.
Post-Installation Customization
• NEXT STOP: Customizing that app after its installed.• For nearly all Windows applications, customization is stored
in the registry.• Whole-machine customization in HKLM.• Per-user customization in HKCU.
• The easiest way to determine post-installation customization is using that same “diff” packager tool.
• Snapshot after installation• Make a configuration change• Re-snapshot• Package registry change• Distribute the registry change.
Post-Installation Customization
• HKLM is easy to manipulate.• Settings are per-machine.
• HKCU can be a little more difficult.• User must be logged in for HKCU hive to be loaded.
• This process gets waaaaaay easier with Group Policy Preferences.
• Are you seriously not using them yet?• With GPPs, creating custom registry changes is crazy easy.
DEMOUsing “diffs” for Configuration Control

Group Policy Preferences
• Applications and Windows itself store its configurations either in the registry or in files.
• What then we need is…● A toolset that allows admins to easily input custom
configurations without requiring coding.● Environment variables, files, folders, INI files, registry settings,
network shares, shortcuts.● Data sources, devices, folder options, local users and groups,
network options, power options, printers, scheduled tasks, services.
• Solution: GPPs!

Part IIThe Science of Software Deployment

From Package to Software
• Now that you’ve got a software package, you need to get it deployed to machines.
• Multiple software deployment solutions exist, with various price points…• Microsoft ConfigMgr • Microsoft SCE • Altiris• Kaseya• Kace KBOX• Active Directory• MDT
Free
Not Free
One Way: GP Software Installation
• Group Policy Software Installation (GPSI) is free and has already bromanced your Active Directory● Generally limited to MSI installations.
• Although ZAP files allow EXE installations.
● Careful: Deleting a GP in the wrong way can automatically uninstall software everywhere.
● GPs have no reporting component. No way to know where failures have occurred.
• …but, it is free.
One Way: GP Software Installation
• Four Steps to installing software via GPSI:● Obtain a “silenced” MSI installation package● Create a software distribution shared folder● Create a GPO● Assign or Publish the software
One Way: GP Software Installation
• Four Steps to installing software via GPSI:● Obtain a “silenced” MSI installation package● Create a software distribution shared folder● Create a GPO● Assign or Publish the software
• Assignment vs. Publishing● When a package is Assigned, the software isn’t downloaded and
installed until its initial use. • The user must click its icon to start the process.• Eliminates software that users don’t use, but increases the time to start on
first use.
● When a package is Published, it appears in Add/Remove Programs.
• The user must choose to “Install a program from the network”• You cannot Publish to Computer objects
Another Way: Task Sequences in Microsoft Deployment Toolkit• MDT includes multiple ways to inject
applications directly into installed OS images.● Select them at deployment time.● Add them into a Task Sequence.
• Deploying apps via MDT starts with repackaging…
Another Way: Task Sequences in Microsoft Deployment Toolkit• Applications without source files is used for
deploying prepackaged applications.• Application bundles link packages together.
Injecting Apps During MDT Installation
• Create new applications in MDT.
Injecting Apps During MDT Installation
• Once added, applications can be selected during the installation.
Injecting Apps During MDT Installation
● Alternatively,app installscan be addedto a TaskSequence.
● Adding thereeliminates thequestionsduring install.
