Create a Custom Detection Script for inFlow Cloud (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 inFlow Cloud using PowerShell.

How to Create a Custom Detection Script for inFlow Cloud

inFlow Cloud (Registry Detection Method)

• Install the version of inFlow Cloud you want to deploy on a test box or VM
  • Check out the following posts for further details
    • inFlow Cloud Silent Install (How-To Guide)
    • inFlow Cloud Install and Uninstall (PowerShell)
• Open Windows PowerShell ISE by Right-Clicking on Windows PowerShell ISE and selecting Run as Administrator
• Copy the following code into the Windows PowerShell ISE

## Check for inFlow Cloud (Registry Detection Method)
$inFlowCloud = Get-ChildItem -Path "HKCU:\Software\Microsoft\Windows\CurrentVersion\Uninstall" | Get-ItemProperty | Where-Object {$_.DisplayName -match 'inFlow Cloud' } | Select-Object -Property DisplayName, DisplayVersion, PSChildName
$inFlowCloud.DisplayVersion
$inFlowCloud.PSChildName
