Please provide us with some more information. Does Dolphin crash? Does the executable file appear to do nothing (not even crash)? Does Dolphin hang (i.e. the taskbar shows Dolphin - Not Responding)?
Your profile says you're using Dolphin 2.0, which is ancient, so I assume that was a mistake or something. At any rate, try using some of the latest development revisions (such as 5.0-10648) here first: https://dolphin-emu.org/download/
