Troubleshooting Marketing Automation service start for XP 10.2 installation on Windows 11

The problem

When installing Sitecore XP 10.2 for IIS 10.0.2*** like the one supplied for Windows 11, you will likely hit an error of Marketing Automation service unable to start. The SIF error starts with:

Install-SitecoreConfiguration : Failed to start service 'Sitecore Marketing Automation Engine'

That occurs due to a failure caused by TLS 1.3 so that the service fails to communicate with XConnect.

The solution

Just download and run this script prior to executing XP0-SingleDeveloper.ps1 main installation script. It will disable TLS 1.3 over TCP for the local IIS (beware as it may affect other non-Sitecore sites).

Alternatively, here's the code:

New-Item `
   'HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.3\Server' `
   -Force | Out-Null
    
New-ItemProperty `
   -path 'HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.3\Server' `
   -name 'Enabled' -value '0' -PropertyType 'DWord' -Force | Out-Null
    
New-ItemProperty `
   -path 'HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.3\Server' `
   -name 'DisabledByDefault' -value 1 -PropertyType 'DWord' -Force | Out-Null

Hope that helps!
