Create a Custom Detection Script for Unity Hub (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 Unity Hub For Windows using PowerShell.

How to Create a Custom Detection Script for Unity Hub

Unity Hub (File Detection Method)

## Check for Unity Hub (File Detection Method)
$UnityHubExe = (Get-ChildItem -Path "C:\Program Files\Unity Hub\Unity Hub.exe","C:\Program Files (x86)\Unity Hub\Unity Hub.exe" -ErrorAction SilentlyContinue)
$UnityHubExe.FullName
$UnityHubPath = $($UnityHubExe.FullName).Replace("C:\Program Files\","").Replace("C:\Program Files (x86)\","")
$FileVersion = (Get-Item -Path "$($UnityHubExe.FullName)" -ErrorAction SilentlyContinue).VersionInfo.FileVersion

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

Example: 

If([String](Get-Item -Path "$Env:ProgramFiles\Unity Hub\Unity Hub.exe","${Env:ProgramFiles(x86)}\Unity Hub\Unity Hub.exe" -ErrorAction SilentlyContinue).VersionInfo.FileVersion -ge "3.2.0"){
Write-Host "Installed"
}

Unity Hub (Registry Detection Method)

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

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

Example: 

If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Unity Technologies - Hub','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\Unity Technologies - Hub' -Name DisplayVersion -ea SilentlyContinue) -ge '3.2.0') {
Write-Host "Installed"
}
