Windows 10: Server 2022 Datacenter Activation Failing

Just attempted to activate this copy of Server 2022 Datacenter and it failed with 0xC004C003 "The activation server determined the specified product key is blocked"I have a COA and this is a brand new install. What can I do to troubleshoot this further?I've attempted to uninstall and reinstall using slmgr, unfortunately /ato fails with the same code.Any ideas? Is there a telephone number I can call to get an unblock code perhaps?

Activate Windows Server 2022 Datacenter on Hyper-V Host with Windows Server 2019 Datacenter

Hi!

I tried to aktivate a new VM on my Hyper-V Host.

The Hyper-V Host is a Windows Server 2019 DataCenter Core.

The new VM is a Windows Server 2022 DataCenter (with GUI).

For the activation by Host i use the AVMA-Key for Windows Server 2022 DataCenter but the Server couldn´t be activated with this key.

Why? Isn´t possible to use a WinSrv 2022 DC as guest on a WinSrv 2019 DC Host?

Error to install KB5014665 on Windows Server 2022 DataCenter (0x800f0982)

Hi Support,

I would like to know if Windows Server 2022 Datacenter supports functional level 10 from Windows Server 2019. I intend to downgrade my Windows Server from 2022 to 2019 to Create a LACP teaming NICs.

looking forward to hearing from you.

Cheers,
