You might be unable to assign a license key to a vCenter Server system because of the following reasons.
- The license edition does not match the currently configured resources and features on vCenter Server. For example, while in evaluation mode, you add the vCenter Server system to a Linked Mode group. Then you try to assign a Foundation or an Essentials license key to the vCenter Server system. The operation is unsuccessful because the Foundation and Essentials license editions do not support the Linked Mode feature.
- You assign an incorrect license key.
- Upgrade the license edition to match the currently configured features and resources on vCenter Server. For example, you need a Standard or an Enterprise license key to be able to license a vCenter Server system that is in Linked Mode.
