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 Unreal Commander using PowerShell.

How to Create a Custom Detection Script for Unreal Commander

Unreal Commander (File Detection Method)

## Check for Unreal Commander (File Detection Method)
$UnrealCommanderExe = (Get-ChildItem -Path "C:\Unreal Commander\UnrealCommander32.exe" -ErrorAction SilentlyContinue)
$UnrealCommanderExe.FullName
$UnrealCommanderPath = $($UnrealCommanderExe.FullName).Replace("C:\","")
$FileVersion = (Get-Item -Path "$($UnrealCommanderExe.FullName)" -ErrorAction SilentlyContinue).VersionInfo.FileVersion

## Create Text File with Unreal Commander File Detection Method
$FilePath = "C:\Windows\Temp\Unreal_Commander_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([String](Get-Item -Path `"`$Env:HomeDrive\$UnrealCommanderPath`" -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 Unreal Commander Detection Method script required to detect the current version of Unreal Commander that is installed on the device you are running the script from.

Example:

If([String](Get-Item -Path "$Env:HomeDrive\Unreal Commander\UnrealCommander32.exe" -ErrorAction SilentlyContinue).VersionInfo.FileVersion -ge "4.2.1.1559"){
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}

Unreal Commander (Registry Detection Method)

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

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

Example:

If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\UnrealCommander_is1','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\UnrealCommander_is1' -Name DisplayVersion -ea SilentlyContinue) -ge '4.2.1.1559') {
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}
