The server hosting the Engine service should have significant CPU, disk, and memory for all but the smallest installations.
The Engine runs on any of the following Windows Servers:
Windows Server 2022
Windows Server 2019
Windows Server 2016
The Engine host must be joined to the domain
NOTE:Micro Focus strongly recommends that you install the Engine on a member server and not on a domain controller. This recommendation might be a requirement in a future release.
