Create a Custom Detection Script for ConnectWise Control (ScreenConnect) (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 ConnectWise Control (ScreenConnect) using PowerShell.

How to Create a Custom Detection Script for ConnectWise Control (ScreenConnect)

ConnectWise Control (ScreenConnect) (File Detection Method)

## Check for ConnectWise Control (ScreenConnect) (File Detection Method)

$ScreenConnectExe.FullName
$ScreenConnectPath = $($ScreenConnectExe.FullName).Replace("C:\Program Files\","").Replace("C:\Program Files (x86)\","")
$FileVersion = (Get-Item -Path "$($ScreenConnectExe.FullName)" -ErrorAction SilentlyContinue).VersionInfo.FileVersion

$FilePath = "C:\Windows\Temp\ScreenConnect_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([String](Get-Item -Path `"`$Env:ProgramFiles\$ScreenConnectPath`",`"`${Env:ProgramFiles(x86)}\$ScreenConnectPath`" -ErrorAction SilentlyContinue).VersionInfo.FileVersion -ge `"$FileVersion`"){"
Add-Content -Path "$FilePath" -Value "Write-Host `"Installed`""
Add-Content -Path "$FilePath" -Value "Exit 0"
Add-Content -Path "$FilePath" -Value "}"
