CodeTyphon does not support multiple installations which means u can have only one version/instance of CodeTyphon working on ur PC.

It also supports installation only on C: drive on Windows; so if u want to install CodeTyphon on D: drive, then ur doomed.

I have two physical drives installed; a solid state drive is mounted as C:, that is why I do not want to install CodeTyphon on C: drive; that is why I don't use it.

As far as I remember, CodeTyphon contains trunk FPC while I prefer using stable FPC branch; and that is another reason why I don't use CodeTyphon
