Create a Custom Detection Script for Samsung DeX (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 Samsung DeX using PowerShell.

How to Create a Custom Detection Script for Samsung DeX

Samsung DeX (File Detection Method)

## Check for Samsung DeX (File Detection Method)
$SamsungDeXExe = (Get-ChildItem -Path "C:\Program Files\Samsung\Samsung DeX\SamsungDeX.exe","C:\Program Files (x86)\Samsung\Samsung DeX\SamsungDeX.exe" -ErrorAction SilentlyContinue)
$SamsungDeXExe.FullName
$SamsungDeXPath = $($SamsungDeXExe.FullName).Replace("C:\Program Files\","").Replace("C:\Program Files (x86)\","")
$FileVersion = (Get-Item -Path "$($SamsungDeXExe.FullName)" -ErrorAction SilentlyContinue).VersionInfo.FileVersion

## Create Text File with Samsung DeX File Detection Method
$FilePath = "C:\Windows\Temp\Samsung_DeX_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([String](Get-Item -Path `"`$Env:ProgramFiles\$SamsungDeXPath`",`"`${Env:ProgramFiles(x86)}\$SamsungDeXPath`" -ErrorAction SilentlyContinue).VersionInfo.FileVersion -ge `"$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 Samsung DeX Detection Method script required to detect the current version of Samsung DeX that is installed on the device you are running the script from.

Example:

If([String](Get-Item -Path "$Env:ProgramFiles\Samsung\Samsung DeX\SamsungDeX.exe","${Env:ProgramFiles(x86)}\Samsung\Samsung DeX\SamsungDeX.exe" -ErrorAction SilentlyContinue).VersionInfo.FileVersion -ge "2.4.1.18"){
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}

Samsung DeX (Registry Detection Method)

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

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

Example:

If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{0ee140a4-adcc-4974-ad4c-210d225b488c}','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{0ee140a4-adcc-4974-ad4c-210d225b488c}' -Name DisplayVersion -ea SilentlyContinue) -ge '2.4.1.18') {
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.
