Once you've gotten mod manager v 0.53 downloaded, you'll want to set up the directory path for the folder where you installed your game (choose the directory path where your actual DAI.exe is, not the shortcut). I recommend downloading it through the DAI Tools Suite Loader, which will, in the future, let you know when there is an update for mod manager. So, first thing: you'll need to get the most recent mod manager in order for mods to work with patch 8 (the most recent game patch).
