Are you missing Qt5Gui.dll or the Qt framework? (I'm not entirely sure what that error message says, but it looks like it.)
I don't think Qt is usually installed separately, the UOSteam installer probably installs it for you. It might be missing if you copied UOSteam from another computer. Maybe try reinstalling UOSteam?
