Hello.
If you have a VMware vSphere Essentials Kit, you must have registered two licenses which are:
1 vcenter server Essentials license
1 vshpere Essentials license for 6 CPUs
These 2 licenses must be entered and assigned in the VCSA or vcenter Server.

If you have a VCSA inside one of the ESXi host, you must also enter and assign the license vshpere Essentials for 6 CPUs license on that ESXI host, so that you can boot and load the VCSA.
