Create a Custom Detection Script for the AWS Command Line Interface (CLI) (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 the AWS Command Line Interface (CLI) using PowerShell.

How to Create a Custom Detection Script for the AWS Command Line Interface (CLI)

AWS Command Line Interface (CLI) (Registry Detection Method)

## Check for AWS Command Line Interface (CLI) (Registry Detection Method)
$AWSCLI = Get-ChildItem -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall","HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall" | Get-ItemProperty | Where-Object {$_.DisplayName -like 'AWS Command Line Interface*' } | Select-Object -Property DisplayName, DisplayVersion, UninstallString
$AWSCLI.DisplayVersion
$GUID = $AWSCLI.UninstallString -replace 'MsiExec.exe /I', '' -replace 'MsiExec.exe /X', ''

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

Example:

If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{3B3444ED-2B51-47CB-B356-C81DF0B0A684}','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{3B3444ED-2B51-47CB-B356-C81DF0B0A684}' -Name DisplayVersion -ea SilentlyContinue) -ge '2.7.19.0') {
Write-Host "Installed"
}
