I know I'm necroing an old thread, but why would I just open my DA:O install folder? You just said click on the folder with no other explanation and then to click on the non-companion NPC folder's. So far the installer doesn't do anything. After I run it and check my DA:O install, nothing is added or removed so I'm curious as to what the installer application actually does. Running it a subsequent time merely opens the executable paired along with the installer - which does nothing with any combination of choosing options from different tabs and clicking install.
