Broadcom transitioned VMware away from perpetual licensing to a subscription-based model. Organizations must now purchase subscriptions like VMware vSphere Foundation (VVF) or VMware Cloud Foundation (VCF) through authorized resellers to obtain legitimate, fully supported ESXi license keys. How to Properly Apply Your ESXi License Key
Having a valid ESXi license key is crucial for several reasons:
If your host is currently managed by vCenter Server and uses Distributed Virtual Switches (DVS), applying a lower-tier license key that lacks DVS support will result in an error. The system will prevent you from downgrading the license until the dependencies are removed. Step-by-Step Fixes for ESXi License Key Issues vmware esxi license key fixed

If you attempt to apply a license key and receive an error message, the root cause usually falls into one of the following categories: 1. Version Mismatch
Understanding VMware ESXI License Key Expiration and Fixes VMware ESXi is a bare-metal hypervisor that partitions physical servers into multiple virtual machines. When deploying ESXi, managing license keys is critical to maintaining continuous operations. A common challenge administrators face is the "Evaluation Mode" expiration, which locks management capabilities after 60 days. If you assign a license
However, once those 60 days expire, the environment stops operating normally. Virtual machines cannot be powered on, vCenter integration fails, and the host enters a "disconnected" state. If you're running a VCF (VMware Cloud Foundation) environment, evaluation license expiration can create a particularly nasty circular dependency: hosts need licenses to power on management VMs, but the VCF Operations appliance must be running to assign those licenses.
By following the guidelines and best practices outlined in this article, you'll be well on your way to efficiently managing your VMware ESXi license keys and maintaining a robust and reliable virtualization environment.
Navigating the complexities of VMware ESXi licensing has become increasingly critical following Broadcom's shift away from perpetual licenses toward a subscription-only model. When faced with a "license key expired" error, your virtual machines (VMs) will fail to power on, effectively rendering your server unusable.
If you assign a license, but after a reboot ESXi reverts to evaluation mode, the license key is not “fixed” in the persistent storage. To fix:
