Installing Sage 50 2023 on server drive d: not c:

I'm upgrading from an old server to a new server and needing to install Sage 50 2023 to the new server.  The old server program was on Drive D: and networked with two other computers.  When I install to D: on new server, the program will not run Smartpost.  Do we have to install on drive C: only or can we install on Drive D:?
