Are you upgrading your exploit, or just your dash?
If you are updating your exploit, grab uxe-complete fromt he usual spots, and set it up according to its readme.
if you are just updating your dash, are you refering to your ms-dash or your after market dash.
if its your after-market dash, then find out where your current dash is loaded from (usually c:\evoxdash.xbe or c:\fonts\dash\default.xbe or e:\dash\default.xbe) and replace it with your new dash.
