How to set Excel 2010 as default for open excel files instead of 2

[Steven]

I recently installed Office 2010 Beta. When i click on an excel file it
automatically opens in Excel 2007. How do i make Excel 2010 default when i
open an excel file?

--From Run (Windows Start Button) type your path to excel2010

and Hit Enter
