Create a Custom Detection Script for Opera 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 Opera Browser using PowerShell.

How to Create a Custom Detection Script for Opera Browser

Opera Browser (File Detection Method)

## Check for Opera Browser (File Detection Method)
$OperaExe = (Get-ChildItem -Path "C:\Program Files\Opera\opera.exe","C:\Program Files (x86)\Opera\opera.exe" -ErrorAction SilentlyContinue)
$OperaExe.FullName
$OperaPath = $($OperaExe.FullName).Replace("C:\Program Files\","").Replace("C:\Program Files (x86)\","")
$FileVersion = (Get-Item -Path "$($OperaExe.FullName)" -ErrorAction SilentlyContinue).VersionInfo.FileVersion

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

Example:

If([String](Get-Item -Path "$Env:ProgramFiles\Opera\opera.exe","${Env:ProgramFiles(x86)}\Opera\opera.exe" -ErrorAction SilentlyContinue).VersionInfo.FileVersion -ge "90.0.4480.54"){
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}

Opera Browser (Registry Detection Method)

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

## Create Text File with Opera Browser Registry Detection Method
$FilePath = "C:\Windows\Temp\Opera_Browser_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\$($Opera.PSChildName)','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\$($Opera.PSChildName)' -Name DisplayVersion -ea SilentlyContinue) -ge '$($Opera.DisplayVersion)') {"
Add-Content -Path "$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 Opera Browser Detection Method script required to detect the current version of Opera 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\Opera 90.0.4480.54','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\Opera 90.0.4480.54' -Name DisplayVersion -ea SilentlyContinue) -ge '90.0.4480.54') {
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}
