The error code 0xC004C020 indicates that the Multiple Activation Key (MAK) has exceeded its limit. This typically occurs when the number of activations allowed for that specific MAK has been reached. Since you are trying to activate Windows Server Datacenter on a VMware host, here are some steps you can take to resolve this issue:
- Contact Microsoft Licensing Activation Centers: Since the MAK has exceeded its limit, you will need to request more activations. You can do this by contacting the Microsoft Licensing Activation Centers.
- Verify the MAK: Ensure that the MAK you are using is the correct one provided by Microsoft for your licenses. If there is any doubt, it's best to confirm with Microsoft.
- Check Activation Limits: If you are using the same MAK across multiple virtual machines, ensure that you are within the allowed activation limits for your licenses.
- Consider KMS Activation: If you have a large number of servers, consider using Key Management Service (KMS) for activation instead of MAK, as it allows for easier management of activations across multiple machines.
If the issue persists after following these steps, further assistance from Microsoft support or your licensing partner may be necessary.
