powerpkg

A Windows-exclusive software package facilitator; an installation script on steroids for enterprise MDM-hosted packages, with optional actions, conditions and exceptions as core features. It is deliberately designed to behave in accordance to an adjacent configuration file, ensuring a low learning curve, code standardization among every instance, and easy software updates (when available).

Requirement

Before reading through this documentation, please note that a minimum of PowerShell 2.0 is required to utilize this project. However, PowerShell 3.0 or higher is recommended.

Getting Started

To begin testing powerpkg:

(1): Clone this repository or download it as a ZIP file.

(2): Invoke powerpkg.ps1:

powershell.exe -NoProfile -ExecutionPolicy Unrestricted -File "contrib\examplepackage\powerpkg.ps1"

(3): And that's it!

NOTE:

To discover basic usage of powerpkg, refer to the How It Works segment of this README.

How It Works

(1): Save the following XML element inside a package.xml file alongside powerpkg.ps1:

<Package>
</Package>

(2): Copy the following script configuration XML element and paste it inside the <Package> XML element:

<Configuration>
	<PackageName>Example Package</PackageName>
	<BlockHost></BlockHost>
	<SuppressNotification>false</SuppressNotification>
</Configuration>

(3): Copy the following task entry XML element and paste it below the <Configuration> XML element:

<TaskEntry>
	<TaskName>Example Task Entry</TaskName>
	<Executable>powershell.exe -NoProfile Write-Host "Hello World!"</Executable>
</TaskEntry>

(4): Ensure your package file (package.xml) appears as this example:

<Package>
	<Configuration>
		<PackageName>Example Package</PackageName>
		<BlockHost></BlockHost>
		<SuppressNotification>false</SuppressNotification>
	</Configuration>
	<TaskEntry>
		<TaskName>Example Task Entry</TaskName>
		<Executable>powershell.exe -NoProfile Write-Host "Hello World!"</Executable>
	</TaskEntry>
</Package>

(5): Invoke powerpkg.ps1:

powershell.exe -NoProfile -ExecutionPolicy Unrestricted -File "powerpkg.ps1"

(6): As powerpkg.ps1 is running, you will notice output similar to the following example:

Initiating Package (Example Package):

Host                       : examplehost1
Operating System (Windows) : 6.3
Userspace Architecture     : AMD64
User                       : misterpeguero

----

Configuration Importation  : True
Suppress Notification      : False

----

(1) Example Task Entry:
[powershell.exe -NoProfile Write-Host "Hello World!"]

Hello World!

OK: (0)

----

Package Results (Example Package):

Tasks Processed : 1
 ^
 |
 |---- Success : 1
 +---- Failure : 0

OK: (0)

(7): And that's it!

The last line in the example output above (OK: (0)) solely reports the exit code of powerpkg.ps1. In this case, the zero exit code indicates a successful package deployment. Specified executables also report an exit code upon their invocation and have an influence on the exit code of powerpkg.ps1.

NOTE:

If powerpkg.ps1 terminates with a non-zero exit code, determine its meaning in the Debugging segment of this README.

To discover in-depth usage of powerpkg, refer to the Package File segment of this README.

Package File (`package.xml`)

A package file is a configuration file of powerpkg.ps1 that consists of instructions that:

Specify how powerpkg.ps1 should behave, using one <Configuration> XML element.
What executables to invoke and how to invoke them, using one or more <TaskEntry> XML elements.

And are typically presented in the following manner:

<Package>
	<Configuration>
		<PackageName></PackageName>
		<BlockHost></BlockHost>
		<SuppressNotification></SuppressNotification>
	</Configuration>
	<TaskEntry>
		<TaskName></TaskName>
		<Executable></Executable>
		<OperatingSystem></OperatingSystem>
		<Architecture></Architecture>
		<TerminateProcess></TerminateProcess>
		<TerminateMessage></TerminateMessage>
		<SuccessExitCode></SuccessExitCode>
		<ContinueIfFail></ContinueIfFail>
		<VerifyInstall></VerifyInstall>
		<SkipProcessCount></SkipProcessCount>
	</TaskEntry>
</Package>

Which, with a bit of customization, can become the following example:

<Package>
	<Configuration>
		<PackageName>Example Package</PackageName>
		<BlockHost>examplehost1,examplehost2</BlockHost>
		<SuppressNotification>false</SuppressNotification>
	</Configuration>
	<TaskEntry>
		<TaskName>Example Task Entry</TaskName>
		<Executable>powershell.exe -NoProfile Write-Host "Hello World!"</Executable>
		<OperatingSystem>6.1</OperatingSystem>
		<Architecture>AMD64</Architecture>
		<TerminateProcess>exampleprocess</TerminateProcess>
		<TerminateMessage>Example Program will terminate. Press OK to continue.</TerminateMessage>
		<SuccessExitCode>1234</SuccessExitCode>
		<ContinueIfFail>true</ContinueIfFail>
		<VerifyInstall>[Program]Example Program</VerifyInstall>
		<SkipProcessCount>false</SkipProcessCount>
	</TaskEntry>
	<TaskEntry>
		<TaskName>Another Example Task Entry</TaskName>
		<Executable>powershell.exe -NoProfile Write-Host "Hello New England!"</Executable>
	</TaskEntry>
	<TaskEntry>
		<TaskName>Yet Another Example Task Entry</TaskName>
		<Executable>msiexec.exe /i "[Package]example_program.msi" /qn /norestart</Executable>
		<VerifyInstall>[Program]Example Program</VerifyInstall>
	</TaskEntry>
</Package>

To further familiarize yourself with powerpkg (and especially the above examples), continue reading the Script Configuration and Task Entry segments of this README. Examining the contents of the \contrib\examplepackage directory is also encouraged.

Script Configuration (`<Configuration>`)

The <Configuration> XML element allows for specifying how powerpkg.ps1 should behave. If <Configuration> is nonexistent or no values are specified within package.xml, the default values for the parameters mentioned below are used.

<Configuration> should be specified only once within package.xml.

`PackageName`

Required: No

Purpose: Allows for specifying a custom name for a package.

Default Value: The name of the package directory.

Example Value:
<PackageName>Example Package</PackageName>

`BlockHost`

Required: No

Purpose: Prevents specified hosts from processing a package.

Default Value: null

Example Value:
<BlockHost>examplehost1</BlockHost>

<BlockHost>examplehost1,examplehost2</BlockHost>
NOTE:

A range of hosts can also be blocked, as well. If you have a set machines whose first several characters are identical, such as the following example:
ABCDE1111
ABCDE2222
ABCDE3333
ABCDE4444
ABCDE5555
You can block the list of machines mentioned above by specifying the following:
<BlockHost>ABCDE</BlockHost>

`SuppressNotification`

Required: No

Purpose: Prevents a balloon notification from displaying upon a successful deployment.

Default Value: true

Example Value:
<SuppressNotification>true</SuppressNotification>

<SuppressNotification>false</SuppressNotification>

Task Entry (`<TaskEntry>`)

The <TaskEntry> XML element allows for specifying what executables to invoke and how to invoke them.

Because of its purpose, <TaskEntry> can also be specified more than once within package.xml.

`TaskName`

Required: Yes

Purpose: The title for an individual task entry.

<TaskName>Install Program</TaskName>

NOTE:

You can temporarily skip task entries for the sole purpose of debugging and testing packages, by specifying # as the first character in this fashion:
<TaskName>#Install Program</TaskName>

`Executable`

Required: Yes

Purpose: An executable file/path to invoke.

Subparamaters:

Subparameter Description

[Package] Allows for specifying a file or directory located within a package directory.

NOTE:

Before calling powershell.exe, ensure to specify the -NoProfile parameter (powershell.exe -NoProfile Example-Command), to minimize the risk of arbitrary code execution.

Whitespace and Quotation Marks

When specifying an executable path or arguments containing whitespace, it is recommended to surround such text with double quotation marks.

For individual file and/or directory names containing whitespace, such items should be surrounded by single quotation marks. However, note that this tip solely applies to arguments, and not executable paths themselves.

Example: powershell.exe "[Package]'an example.ps1'" or "C:\White Space\example.exe" /argument "D:\'More White Space'\Directory"

It is also recommended to always surround files and/or directories specified with the [Package] parameter with double quotation marks, to prevent I/O exceptions from being thrown with the usage of whitespace within the directory path of a package directory.

Environment Variables

Unfortunately, at this time, powerpkg does not support the independent usage of environment variables. However, as a workaround, you can:

Call cmd.exe in the following manner: cmd.exe /c notepad.exe %SYSTEMDRIVE%\test.txt.
Call powershell.exe in the following manner: powershell.exe Start-Process -FileName notepad.exe -ArgumentList $env:SYSTEMDRIVE\test.txt -Wait.

Examples

Here are other valid example use cases of the Executable parameter:

<Executable>ipconfig.exe</Executable>

<Executable>msiexec.exe /i "[Package]example.msi" /qn /norestart</Executable>

<Executable>cmd.exe /q /c "[Package]example.bat"</Executable>

<Executable>"[Package]example.exe"</Executable>

<Executable>"[Package]example_directory\'example file with whitespace.exe'"</Executable>

`OperatingSystem`

Required: No

Purpose: The operating system a task entry should be processed under.

When utilizing this parameter, you will want to specify the NT kernel version number of a specific Windows operating system:

Windows Operating System	NT Kernel Version
10	`10.0`
8.1	`6.3`
8	`6.2`
7	`6.1`
Vista	`6.0`

And specify a NT kernel version number in this fashion:

<OperatingSystem>6.3</OperatingSystem>

NOTE:

Because the OperatingSystem parameter determines to find a match between a specified value (6.1) and the complete version number of a Windows operating system (6.1.7601), the value of 6.1.7601, which indicates a specific build of Windows 7, can be specified, as well.

`Architecture`

Required: No

Purpose: The userspace architecture a task entry should be processed under.

For executable invocations that depend on a specific architectural environment, you will want to specify the following for:

AMD64 (x64 in Microsoft terminology) environments:

<Architecture>AMD64</Architecture>

x86 environments:

<Architecture>x86</Architecture>

`TerminateProcess`

Required: No, except when utilizing the TerminateMessage parameter.

Purpose: A process, or list of process, to terminate prior to executable invocation.

<TerminateProcess>explorer</TerminateProcess>

<TerminateProcess>explorer,notepad</TerminateProcess>

`TerminateMessage`

Required: No

Purpose: A message to display to an end-user prior to the termination of processes. Used in conjunction with the TerminateProcess parameter.

<TerminateMessage>File Explorer will terminate. When prepared, click on the OK button.</TerminateMessage>

`SuccessExitCode`

Required: No

Purpose: Non-zero exit codes that also determine a successful task entry.

NOTE:

The 0 exit code is automatically applied to any specified value, regardless as to whether or not it is explicitly specified.

<SuccessExitCode>10</SuccessExitCode>

<SuccessExitCode>10,777,1000</SuccessExitCode>

`ContinueIfFail`

Required: No

Purpose: Specify as to whether or not to continue with remaining task entires if a specific task entry fails.

When explicitly utilizing the ContinueIfFail parameter and specifying the following value:

Value	Result
`true`	`powerpkg.ps1` will continue processing remaining task entires. A task entry set to continue when resulting in a non-zero exit code will not alter the exit code of `powerpkg.ps1`.
`false` (Default)	`powerpkg.ps1` will fail and result in a non-zero exit code.

And specify your desired value in this fashion:

<ContinueIfFail>true</ContinueIfFail>

`VerifyInstall`

Required: No

Purpose: Skip a task entry if a program, hotfix, file/directory path, or a specific version of an executable file exist.

Subparamaters:

Subparameter Description Additional Arguments Additional Arguments Required?

[Hotfix] Verify the existence of a hotfix.

[Path] Verify the existence of a file or directory path.

[Vers_File] Verify the file version of an executable file. [Build:] Yes

[Vers_Product] Verify the product version of an executable file. [Build:] Yes

[Program] Verify the existence of an installed program name or product code. [Build:] No

NOTE:

When utilizing the VerifyInstall parameter, you must specify one of the following subparamaters mentioned above.

The usage of PowerShell environment variables, such as $env:SYSTEMDRIVE, is supported by the VerifyInstall parameter.

The usage of quotation marks is not a requirement, even for paths that contain whitespace.

[Build:] Argument

As you may have noticed, certain parameters take advantage of a [Build:] argument, which allows you to verify the existence of a specific version number associated with an installed program or executable file. To use this argument, you must specify it at the right side of a provided VerifyInstall value, then insert a version number on the right side of its colon. Take the following as an example:

<VerifyInstall>[Vers_Product]C:\example_file.exe[Build:1.0]</VerifyInstall>

However, unlike the OperatingSystem parameter, whatever [Build:] version number is specified must be identical to the version number of an installed program or executable file.

[Vers_] Subparameters

To utilize the [Vers_*] subparameters, you will need to retrieve the file or product version numbers from an executable file. To do so:

Within PowerShell, invoke the following command:

[System.Diagnostics.FileVersionInfo]::GetVersionInfo("C:\example_file.exe") | Select FileVersion, ProductVersion

And you will notice the following output:

FileVersion       ProductVersion
-----------       --------------
1.0               1.0

Then, specify either outputted value inside the [Build:] argument in the following manner:

<VerifyInstall>[Vers_File]C:\example_file.exe[Build:1.0]</VerifyInstall>

<VerifyInstall>[Vers_File]$env:SYSTEMDRIVE\example_file.exe[Build:1.0]</VerifyInstall>

<VerifyInstall>[Vers_Product]C:\example_file.exe[Build:1.0]</VerifyInstall>

[Program] Subparameter

To utilize the [Program] subparameter, you can verify the existence of a:

Product Code:

Open the Programs and Features applet of the Windows Control Panel, and retrieve the name of the installed program you wish to verify the existence of:

Within PowerShell, enter the following command:

Get-ChildItem HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall | % {Get-ItemProperty $_.PSPath} | ? {$_.DisplayName -eq "Example Program"} | Select PSChildName

Within PowerShell, enter the following command, if you're utilizing a x86 program on an AMD64 system:

Get-ChildItem HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall | % {Get-ItemProperty $_.PSPath} | ? {$_.DisplayName -eq "Example Program"} | Select PSChildName

And you will notice the following output:

PSChildName
-----------
{00000000-0000-0000-0000-000000000000}

Then, specify the outputted value in this fashion:

<VerifyInstall>[Program]{00000000-0000-0000-0000-000000000000}</VerifyInstall>

Or if you wish to verify the existence an installed program's respective version number along with its product code:
```
<VerifyInstall>[Program]{00000000-0000-0000-0000-000000000000}[Build:1.0]</VerifyInstall>
```

Program Name:
- Open the Programs and Features applet of the Windows Control Panel, and retrieve the name of the installed program you wish to verify the existence of:
- Then, specify a program name in this fashion:
```
<VerifyInstall>[Program]Example Program</VerifyInstall>
```
- Or if you wish to verify the existence an installed program's respective version number along with its name:
```
<VerifyInstall>[Program]Example Program[Build:1.0]</VerifyInstall>
```

Examples

Here are other valid example use cases of the VerifyInstall parameter and its respective subparameters:

<VerifyInstall>[Hotfix]KB0000000</VerifyInstall>

<VerifyInstall>[Path]C:\example_file.exe</VerifyInstall>

<VerifyInstall>[Path]C:\example_directory</VerifyInstall>

<VerifyInstall>[Path]C:\example directory with whitespace</VerifyInstall>

<VerifyInstall>[Path]$env:SYSTEMDRIVE\example_directory</VerifyInstall>

<VerifyInstall>[Path]HKLM:\registry_path</VerifyInstall>

<VerifyInstall>[Path]env:\ENVIRONMENT_VARIABLE</VerifyInstall>

`SkipProcessCount`

Required: No

Purpose: Specify as to whether or not a processed task entry should be counted as such and contribute to the overall total of processed task entries, whether it succeeds or fails.

When explicitly utilizing the SkipProcessCount parameter and specifying the following value:

Value	Result
`true`	`powerpkg.ps1` will not count a processed task entry as such.
`false` (Default)	`powerpkg.ps1` will count a processed task entry as such.

And specify your desired value in this fashion:

<SkipProcessCount>true</SkipProcessCount>

Debugging

Exit Codes

Code	Description
1	A task entry terminated with a non-zero exit code.
2	An exception rose from a task entry during its executable invocation process.
3	Initial task entry processing failed.
4	A host has been prevented from processing a package.
5	A package file was not found.
