Hi Leo Jones,
Thank you for the additional information.
Since you've already tried the Activation Troubleshooter and it did not resolve the issue, I'd like to share a Microsoft Q&A discussion that describes a similar scenario involving error 0xC004F069: Upgrade Win 11 home to Pro Code 0xC004F069 - Microsoft Q&A
In that case, the accepted solution was to use the generic Windows 11 Pro product key to trigger the edition upgrade first and then activate Windows using the purchased Pro key afterward. The article also suggests verifying the current edition, checking target editions with DISM and confirming that the Pro key matches the edition being installed.
Please review the article and let me know whether you've already tried those specific steps, particularly the generic Pro key method and the DISM edition checks. If so, please also share the exact results or error messages you received so I can help determine the next steps.
