Can't add CSVLKs for Windows 10 activation to VAMT 3.1

Symptoms
When you try to add a Windows 10 Key Management Service (KMS) host key (CSVLK) or a Windows Server 2012 R2 for Windows 10 CSVLK into Volume Activation Management Tool (VAMT) 3.1 (version 10.0.10240.0), you receive the following error message:

The specified product key is invalid, or is unsupported by this version of VAMT. An update to support additional products may be available online.


VAMT Error
Cause
This issue occurs because VAMT 3.1 does not contain the correct pkconfig files to recognize this kind of key.

Status
Microsoft is researching this problem and will post more information in this article when the information becomes available.
