Why postgres install requires physical access to server in windows

["Andrus" <eetasoft@xxxxxxxxx>]

Remote install of Postgres 8.1.3 using Windows installer binary package is
not working (says that console mode is required) even when RDP client is
started with

mstsc /console

switch.

However, using installer package, creating cluster and server process
manually works OK from RDP client!

Any idea why Postgres installer requires physical access to server to
install Postgres ?
