Create a Custom Detection Script for Univerge Blue Connect (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 Univerge Blue Connect using PowerShell.

How to Create a Custom Detection Script for Univerge Blue Connect

Univerge Blue Connect (File Detection Method)

## Check for Univerge Blue Connect (File Detection Method)
$UnivergeBlueConnectExe = (Get-ChildItem -Path "C:\Program Files\UNIVERGE BLUE CONNECT\UNIVERGE BLUE CONNECT.exe" -ErrorAction SilentlyContinue)
$UnivergeBlueConnectExe.FullName
$UnivergeBlueConnectPath = $($UnivergeBlueConnectExe.FullName).Replace("C:\Program Files\","")
$FileVersion = (Get-Item -Path "$($UnivergeBlueConnectExe.FullName)" -ErrorAction SilentlyContinue).VersionInfo.FileVersionRaw

## Create Text File with Univerge Blue Connect File Detection Method
$FilePath = "C:\Windows\Temp\Univerge_Blue_Connect_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([String](Get-Item -Path `"`$Env:ProgramFiles\$UnivergeBlueConnectPath`" -ErrorAction SilentlyContinue).VersionInfo.FileVersionRaw -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 Univerge Blue Connect Detection Method script required to detect the current version of Univerge Blue Connect that is installed on the device you are running the script from.

Example:

If([String](Get-Item -Path "$Env:ProgramFiles\UNIVERGE BLUE CONNECT\UNIVERGE BLUE CONNECT.exe" -ErrorAction SilentlyContinue).VersionInfo.FileVersionRaw -ge "2.15.187.0"){
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}

Univerge Blue Connect (Registry Detection Method) – All Users Install

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

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

Example:

If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\964a50f1-16e6-52f2-be13-072861cc01e4' -Name DisplayVersion -ea SilentlyContinue) -ge '2.15.187') {
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}
