I have a volume license activation key(MAK) for Win Server 2019 Standard. I installed Windows server 2019 StandardEval on 3 virtual machines which they are on the VMWare Vsphere 6 Essential hypervisor. But it is impossible for me to activate the 3 OS with the key I have (VLSC). Error message: "The product key you entered does not work. Please check it, then try again or enter a new one. (0xc004f050)" So is it possible to activate VMware VM running win serv 2019 with volume key? If not how to manage? Thank you for supporting me because my servers are unusable.
