Create a Custom Detection Script for Google Chrome (PowerShell)

by

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 Google Chrome using PowerShell.

How to Create a Custom Detection Script for Google Chrome

Google Chrome (File Detection Method)

## Check for Google Chrome (File Detection Method)
$GChromeExe = (Get-ChildItem -Path "C:\Program Files\Google\Chrome\Application\chrome.exe","C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" -ErrorAction SilentlyContinue)
$GChromeExe.FullName
$GChromePath = $($GChromeExe.FullName).Replace("C:\Program Files\","").Replace("C:\Program Files (x86)\","")
$FileVersion = (Get-Item -Path "$($GChromeExe.FullName)" -ErrorAction SilentlyContinue).VersionInfo.FileVersion

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

Example: 

If([String](Get-Item -Path "$Env:ProgramFiles\Google\Chrome\Application\chrome.exe","${Env:ProgramFiles(x86)}\Google\Chrome\Application\chrome.exe" -ErrorAction SilentlyContinue).VersionInfo.FileVersion -ge "123.0.6312.58"){
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}

Google Chrome (Registry Detection Method)

## Check for Google Chrome (Registry Detection Method)
$GChrome = Get-ChildItem -Path "HKLM:\SOFTWARE\Google\Update\Clients","HKLM:\SOFTWARE\Wow6432Node\Google\Update\Clients" -ErrorAction SilentlyContinue | Get-ItemProperty | Where-Object {$_.name -match 'Google Chrome' } | Select-Object -Property name, pv, PSChildName
$GChrome.pv
$GChrome.PSChildName

## Create Text File with Google Chrome Registry Detection Method
If(Test-Path "HKLM:\SOFTWARE\Google\Update\Clients\$($GChrome.PSChildName)") { 

$FilePath = "C:\Windows\Temp\Google_Chrome_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Google\Update\Clients\$($GChrome.PSChildName)' -Name pv -ea SilentlyContinue) -ge '$($GChrome.pv)') {"
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
}

ElseIf(Test-Path "HKLM:\SOFTWARE\Wow6432Node\Google\Update\Clients\$($GChrome.PSChildName)") { 

$FilePath = "C:\Windows\Temp\Google_Chrome_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Wow6432Node\Google\Update\Clients\$($GChrome.PSChildName)' -Name pv -ea SilentlyContinue) -ge '$($GChrome.pv)') {"
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 Google Chrome Detection Method script required to detect the current version of Google Chrome that is installed on the device you are running the script from.

Example: 

If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Wow6432Node\Google\Update\Clients\{8A69D345-D564-463c-AFF1-A69D9E530F96}' -Name pv -ea SilentlyContinue) -ge '123.0.6312.58') {
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}
