How to Fix Server 2019 Activation Error: Run “slui.exe 0x2a 0xC004F069”

The Problem

You’re unable to activate a copy of Windows Server 2019 Evaluation edition with your VLSC MAK key

The Cause

Server 2019 Evaluation edition can only be activated with a retail key. This must happen before a Volume Licence Key can be used.

The Fix

We need to use DISM to change the product version/edition

Open an elevated command prompt

1: Get a list of available version upgrade paths by typing:

DISM.exe /Online /Get-TargetEditions

2: Then upgrade to the listed edition by typing:

DISM /Online /Set-Edition:<TargetEdition> /ProductKey:<Product Key from Below Table> /AcceptEula

EG: DISM /Online /Set-Edition:ServerDatacenterCor /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /AcceptEula

    1. Hey Harry,
      Thanks for your kind comment. I’m glad you were able to sort it out. With some luck we won’t have the same issue in the next release!
