Create a Custom Detection Script for ProjectLibre (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 ProjectLibre using PowerShell.

How to Create a Custom Detection Script for ProjectLibre

ProjectLibre (Registry Detection Method)

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

## Create Text File with ProjectLibre Registry Detection Method
$FilePath = "C:\Windows\Temp\ProjectLibre_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\$($ProjectLibre.PSChildName)','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\$($ProjectLibre.PSChildName)' -Name DisplayVersion -ea SilentlyContinue) -ge '$($ProjectLibre.DisplayVersion)') {"
Add-Content -Path "$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 ProjectLibre Detection Method script required to detect the current version of ProjectLibre that is installed on the device you are running the script from.

Example:

If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{com.projectlibre1.main}}_is1','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{com.projectlibre1.main}}_is1' -Name DisplayVersion -ea SilentlyContinue) -ge '1.9.3') {
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}
