Determine BizTalk version using PowerShell

I wrote a very simple PowerShell script which allows you to easily determine the installed BizTalk version and service pack level.

You cannot just look at the version number anymore because it seems SP1 of BizTalk Server 2006 R2 does not update the version number. This means the version numbers for BizTalk 2006 R2 without and with service pack 1 applied are the same. See also my blog post here.

The script will detect any BizTalk version and service pack from 2004 and later. I have tested it on different environments with different BizTalk versions. Please let me know if it is not working

Below is the source, but you can also download it from here.

$versionBTS2006 = "3.5.1602.0"
$versionBTS2006R2 = "3.6.1404.0"
$versionBTS2009 = "3.8.368.0"

}

if ($installedVersion -eq $null)
{
Write-Host "BizTalk Server is not installed on this machine."
Exit
}

Write-Host "BizTalk Server installation found on this machine."
Write-Host "Product version number: $productVersion"
Write-Host "Installed version: $installedVersion"
