Firebird 3 Server Installation side by side, out othe box, with any other Firebird or Interbase versions [CORE5371]

I see that Firebird 3 Server cannot be installed side by side, out of the box, with Firebird 2.x, like MS SQL Server does for always.
Installing Firebird 3 Server means no longer to run applications build with older server!
Our application could affect or by affected by others applications!

This mean for mine the end of using Firebird, manual modification on tens of desktops of users is madness.

Please modify the installer for Firebird 3 in order to be installed side by side, out of the box, with any version of Firebird and Interbase.
