Create a Custom Detection Script for Brave Browser (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 Brave Browser using PowerShell.

How to Create a Custom Detection Script for the Brave Browser

Brave Browser (File Detection Method)

## Check for Brave Browser (File Detection Method)
$Brave = Get-ChildItem -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall","HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall" | Get-ItemProperty | Where-Object {$_.DisplayName -match 'Brave' } | Select-Object -Property DisplayName, InstallLocation
$BraveExe = "$($Brave.InstallLocation)\brave.exe"
$BravePath = $BraveExe.Replace("C:\Program Files\","").Replace("C:\Program Files (x86)\","")
$FileVersion = (Get-Item -Path "$BraveExe" -ErrorAction SilentlyContinue).VersionInfo.FileVersion

## Create Text File with Brave Browser File Detection Method
$FilePath = "C:\Windows\Temp\Brave_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([String](Get-Item -Path `"`$Env:ProgramFiles\$BravePath`",`"`${Env:ProgramFiles(x86)}\$BravePath`" -ErrorAction SilentlyContinue).VersionInfo.FileVersion -ge `"$FileVersion`"){"
Add-Content -Path "$FilePath" -Value "Write-Host `"Installed`""
Add-Content -Path "$FilePath" -Value "}"
Invoke-Item $FilePath

Example:

If([String](Get-Item -Path "$Env:ProgramFiles\BraveSoftware\Brave-Browser\Application\brave.exe","${Env:ProgramFiles(x86)}\BraveSoftware\Brave-Browser\Application\brave.exe" -ErrorAction SilentlyContinue).VersionInfo.FileVersion -ge "89.1.21.73"){
Write-Host "Installed"
}

Brave Browser (Registry Detection Method)

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

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

Example:

If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\BraveSoftware Brave-Browser','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\BraveSoftware Brave-Browser' -Name DisplayVersion -ea SilentlyContinue) -ge '89.1.21.73') {
Write-Host "Installed"
}
