App-V 5 Scripting Context Test

I carried out an App-V 5 scripting context test recently so that I could prove which context the various App-V 5 scripts run in (user or system) when added or published to a machine or user.

App-V 5 Scripting Test Package

I created a very simple App-V 5 package containing Dependency Walker, and added a shortcut to the executable located at [{ProgramFilesX86}]\DependencyWalker\depends.exe.

I also added a script to the Scripts folder called alkane.ps1:

param([string]$message)
add-content "c:\temp\alkane.log" "$message $([bool](([System.Security.Principal.WindowsIdentity]::GetCurrent()).groups -match "S-1-5-32-544")) $([System.Security.Principal.WindowsIdentity]::GetCurrent().Name)" -ErrorAction Stop

It’s a very simple PowerShell script that takes some text as an argument (I pass this to the script so that I know which scripting section it is running from). Each time the script runs it will output the scripting section is has run from, whether the current scripting context is being run as an administrator, and also what account the script is running under.

In my DeploymentConfig.xml file I added the following UserScripts:

  <UserScripts>

      <StartProcess RunInVirtualEnvironment="true">
        <Path>powershell.exe</Path>
        <Arguments>-ExecutionPolicy ByPass -File "[{AppVPackageRoot}]\..\Scripts\alkane.ps1" -message "DeploymentConfig UserScripts StartProcess"</Arguments>
        <Wait RollbackOnError="true"/>
        <ApplicationId>[{ProgramFilesX86}]\DependencyWalker\depends.exe</ApplicationId>
      </StartProcess>

      <ExitProcess>
        <Path>powershell.exe</Path>
        <Arguments>-ExecutionPolicy ByPass -File "[{AppVPackageRoot}]\..\Scripts\alkane.ps1" -message "DeploymentConfig UserScripts ExitProcess"</Arguments>
        <Wait RollbackOnError="false"/>
        <ApplicationId>[{ProgramFilesX86}]\DependencyWalker\depends.exe</ApplicationId>

      </TerminateVirtualEnvironment>

and also the following MachineScripts:

  </MachineScripts>
