Create a Custom Detection Script for the HP Client Management Script Library (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 the HP Client Management Script Library using PowerShell.

How to Create a Custom Detection Script for the HP Client Management Script Library

HP Client Management Script Library (Registry Detection Method)

## Check for HP Client Management Script Library (Registry Detection Method)
$HPCMSL = Get-ChildItem -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall","HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall" | Get-ItemProperty | Where-Object {$_.DisplayName -match 'HP Client Management Script Library' } | Select-Object -Property DisplayName, DisplayVersion, PSChildName
$HPCMSL.DisplayVersion
$HPCMSL.PSChildName

## Create Text File with HP Client Management Script Library Registry Detection Method
$FilePath = "C:\Windows\Temp\HP_CMSL_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\$($HPCMSL.PSChildName)','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\$($HPCMSL.PSChildName)' -Name DisplayVersion -ea SilentlyContinue) -ge '$($HPCMSL.DisplayVersion)') {"
Add-Content -Path "$FilePath" -Value "Write-Host `"Installed`""
Add-Content -Path "$FilePath" -Value "Exit 0"
Add-Content -Path "$FilePath" -Value "}"
Add-Content -Path "$FilePath" -Value "else {"
Add-Content -Path "$FilePath" -Value "Exit 1"
Add-Content -Path "$FilePath" -Value "}"
Invoke-Item $FilePath
  • Click Run Script (F5)
  • A text file will open with the HP Client Management Script Library Detection Method script required to detect the current version of the HP Client Management Script Library that is installed on the device you are running the script from.

Example:

If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{5A1AECCB-E0CE-4D2C-833C-29CCEA959448}_is1','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{5A1AECCB-E0CE-4D2C-833C-29CCEA959448}_is1' -Name DisplayVersion -ea SilentlyContinue) -ge '1.6.9') {
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}

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.
