Create a Custom Detection Script for Mendeley Desktop (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 Mendeley Desktop using PowerShell.

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