RingCentral App: User vs Computer mode installations

The RingCentral App can be installed with an EXE (user mode) or an MSI (computer mode). Unfortunately, both can be installed. We only want the MSI installed.
One of our other vendors uses an MSI for installing, but is capable of doing user and computer mode installations, interactive and unattended. A single installer would make it easier to only allow a single installation of the app in user mode or computer mode.
