Run UIBuilder from icon (make sure you have admin rights)
Select File|Open from the menu
Navigate to the directory where the UI is stored
typically \ProgramFiles\Sony\Everquest II\UI\Default
Select eq2ui.xml and Click Open button

After load, you will see a window with red outline in the view area. This is normal.

In the tree view for Objects, scroll down to find MainHUD and hit the (+) sign next to it to expand the list of items.

Now from the view window (where the red outline is) find the Left/Right arrow keys at the far right of the window. Press the right arrow key until the MainHUD tab is visible.

Click the MainHUD tab and the currently visible windows for that object type will be shown.

You can now select items from the tree view for objects in MainHUD and they will be outlined in the view window.

This the start to modifying objects.

Beyond that, there are layers where some windows will appear to be behind other windows. The best way to manage these is using the controls on the top of the tree view for objects to change the order of the objects so the currently selected object is moved to the top (front).

This should get you going. If you can't get here, you may have much deeper issues to resolve in your system setup.
