Allowing multiple users and accounts to use one installed version of UE

Hello, I am trying to install UE 4.20.3 in a lab setting for multiple users with their own separate Epic accounts. When I install 4.20.3 or any UE version on a computer as one user and then login as another user to access that install, not only does 4.20.3 show up as an option, but the other user is not offered that version as an option. It seems like the version is locked to the user that installed it. A bit of background: All users in this scenario are Administrator.

Any guidance would be appreciated.
