Create a Custom Detection Script for Citrix Workspace (PowerShell)


Microsoft Endpoint Manager Configuration Manager (MEMCM / SCCM) and Microsoft Intune use Detection Rules to determine the presence of Applications & Win32 Apps. The detection rules ensure that application installations only begin to run if the application is not already installed on the device. This article will serve as an informative guide and give you a clear understanding of how to create an updated custom detection script for each new version of Citrix Workspace using PowerShell.

How to Create a Custom Detection Script for Citrix Workspace

Citrix Workspace (File Detection Method)

## Check for Citrix Workspace (File Detection Method)
$WorkspaceExe = (Get-ChildItem -Path "C:\Program Files\Citrix\Citrix WorkSpace*\TrolleyExpress.exe","C:\Program Files (x86)\Citrix\Citrix WorkSpace*\TrolleyExpress.exe" -ErrorAction SilentlyContinue)
$WorkspaceExe.FullName
$WorkspacePath = $($WorkspaceExe.FullName).Replace("C:\Program Files\","").Replace("C:\Program Files (x86)\","")
$FileVersion = (Get-Item -Path "$($WorkspaceExe.FullName)" -ErrorAction SilentlyContinue).VersionInfo.FileVersion

## Create Text File with Citrix Workspace Detection Method
$FilePath = "C:\Windows\Temp\Citrix_Workspace_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([String](Get-Item -Path `"`$Env:ProgramFiles\$WorkspacePath`",`"`${Env:ProgramFiles(x86)}\$WorkspacePath`" -ErrorAction SilentlyContinue).VersionInfo.FileVersion -ge `"$FileVersion`"){"
Add-Content -Path "$FilePath" -Value "Write-Host `"Installed`""
Add-Content -Path "$FilePath" -Value "}"
Invoke-Item $FilePath

Example:

If([String](Get-Item -Path "$Env:ProgramFiles\Citrix\Citrix WorkSpace 2206\TrolleyExpress.exe","${Env:ProgramFiles(x86)}\Citrix\Citrix WorkSpace 2206\TrolleyExpress.exe" -ErrorAction SilentlyContinue).VersionInfo.FileVersion -ge "22.6.0.60"){
Write-Host "Installed"
}

Citrix Workspace (Registry Detection Method)

## Check for Citrix Workspace (Registry Detection Method)
$Workspace = Get-ChildItem -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall","HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall" | Get-ItemProperty `
| Where-Object {$_.DisplayName -match 'Citrix Workspace ' -and $_.DisplayName -notmatch 'Citrix Workspace Inside' -and $_.DisplayName -notmatch 'Citrix WorkSpace Browser' } | Select-Object -Property DisplayName, DisplayVersion
$Workspace.DisplayVersion

## Create Text File with Citrix Workspace Registry Detection Method
$FilePath = "C:\Windows\Temp\Citrix_Workspace_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\CitrixOnlinePluginPackWeb','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\CitrixOnlinePluginPackWeb' -Name DisplayVersion -ea SilentlyContinue) -ge '$($Workspace.DisplayVersion)') {"
Add-Content -Path "$FilePath" -Value "Write-Host `"Installed`""
Add-Content -Path "$FilePath" -Value "}"
Invoke-Item $FilePath
  • Click Run Script (F5)
  • A text file will open with the Citrix Workspace Detection Method script required to detect the current version of Citrix Workspace that is installed on the device you are running the script from.

Example:

If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\CitrixOnlinePluginPackWeb','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\CitrixOnlinePluginPackWeb' -Name DisplayVersion -ea SilentlyContinue) -ge '22.6.0.60') {
Write-Host "Installed"
}

Always make sure to test everything in a development environment prior to implementing anything into production. The information in this article is provided “As Is” without warranty of any kind.
