Create a Custom Detection Script for Adobe Lightroom Classic (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 Adobe Lightroom Classic using PowerShell.

How to Create a Custom Detection Script for Adobe Lightroom Classic

Adobe Lightroom Classic (File Detection Method)

## Check for Adobe Lightroom Classic (File Detection Method)
$LightroomClassicExe = (Get-ChildItem -Path "C:\Program Files\Adobe\Adobe Lightroom Classic\Lightroom.exe" -ErrorAction SilentlyContinue)
$LightroomClassicExe.FullName
$LightroomClassicPath = $($LightroomClassicExe.FullName).Replace("C:\Program Files\","")
$FileVersion = (Get-Item -Path "$($LightroomClassicExe.FullName)" -ErrorAction SilentlyContinue).VersionInfo.FileVersionRaw

## Create Text File with Adobe Lightroom Classic File Detection Method
$FilePath = "C:\Windows\Temp\Adobe_Lightroom_Classic_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([String](Get-Item -Path `"`$Env:ProgramFiles\$LightroomClassicPath`" -ErrorAction SilentlyContinue).VersionInfo.FileVersionRaw -ge `"$FileVersion`"){"
Add-Content -Path "$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 Adobe Lightroom Classic Detection Method script required to detect the current version of Adobe Lightroom Classic that is installed on the device you are running the script from.

Example:

If([String](Get-Item -Path "$Env:ProgramFiles\Adobe\Adobe Lightroom Classic\Lightroom.exe" -ErrorAction SilentlyContinue).VersionInfo.FileVersionRaw -ge "12.4.0.8"){
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}

Adobe Lightroom Classic (Registry Detection Method)

## Check for Adobe Lightroom Classic (Registry Detection Method)
$LightroomClassic = Get-ChildItem -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall","HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall" | Get-ItemProperty | Where-Object {$_.DisplayName -match 'Adobe Lightroom Classic' -and $_.SystemComponent -ne '1' } | Select-Object -Property DisplayName, DisplayVersion, PSChildName
$LightroomClassic.DisplayVersion
$LightroomClassic.PSChildName

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

Example:

If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\LTRM_12_4','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\LTRM_12_4' -Name DisplayVersion -ea SilentlyContinue) -ge '12.4') {
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}
