Just a quick heads-up. I have seen several conversations about installing this or that specific DarqUI window without installing the entire UI. The most recent version of DarqUI has an option to install just the base package without any DarqUI files. For players who don't already use DarqUI, this creates an empty shell directory with only the support files required by the utility. You can choose to automatically load the shell UI when you log in to the game, which will essentially pass through to the default game UI since there are no custom files in the folder. You can optionally use it to install EQ2MAP as well.
1. Choose No for the first and second options, choose whether to install EQ2MAP
2. Click "Do these items automatically"
Once you have the base UI installed, with or without EQ2MAP, you can go back to the Updates page and download any specific DarqUI files you are interested in, one at a time. If you made DarqUI the default UI during setup, you should be able to start the game and log in with your new base UI, without needing to use the /loadui command.
