I have a lab server with VMware ESXi 6.5.0, that has been running for 3+ years. After a power failure it starts up, but any attempt to start an existing VM results in the following error message:
Failed to power on virtual machine VM_NAME. License key has expired. Click here for more details.
The only license key that I have been able to access in the My VMware portal is for "VMware vSphere Hypervisor 7". I have tried to apply that license key to my 6.5.0 server, but it's not accepted.
Any hints?
