Runaway 2 [US] (DVD9 to DVD5)

[BarryB]

The easiest way is to install a game, apply the NoCD/DVD then use Inno to create a new installer with appropriate registry entries!

Inno can make an installer that checks a specific regkey and use it as the default install folder if it's value is a folder, it will then install to that folder in the regkey, otherwise you tell it to pop up a message saying it can't install.
