Install Microsoft Unified Communications Managed API 4.0 Remotely Via PowerShell

Scenario:  You want to install Microsoft’s Unified Communications Managed API 4.0 to multiple servers remotely


  1. Collect your Servers by Querying AD
Import-Module ActiveDirectory
$strOU = "OU=Exchange2016,DC=XYZ,DC=COM"
$servers = get-adcomputer -searchbase $strOU -properties Name -Filter *|  where {$ -like "Ex16-*"} | Select -ExpandProperty Name

2. Copy your Installer File to a folder on each server (or a single network share). We have copied it to C:softwareUCMA.exe on each Exchange Server.

3. Run the Installer by invoking the command on each server.

$servers | %{"Installing UCMA on $_"; Invoke-Command -Computer $_ -ScriptBlock {
    #Set Variables
    $file = "C:softwareUcma.exe" 
    #check to see if its installed
    if (Get-ItemProperty "HKLM:SoftwareMicrosoftWindowsCurrentVersionUninstallUCMA4" -ErrorAction SilentlyContinue) { 
        Write-host "Unified Communications Managed API 4.0 Runtime is already installed." -ForegroundColor Cyan 
        } else {
               If (Test-Path $file){ 
                    Write-host "The installer file exists:$file"  -ForegroundColor Green
                     Write-Host "Installing Microsoft UM API..." -ForegroundColor yellow 
                     $arg = "/quiet /norestart" 
                     $status = (Start-Process $file -ArgumentList $arg -Wait -PassThru).ExitCode 
                     if ($status -eq 0) { write-host "Successfully installed $file" -ForegroundColor Green } 
                     if ($status -ne 0) { write-host "Failed!" -ForegroundColor Red }                           
            } else {Write-host "$file does not exist" -ForegroundColor red}
