After installing, set riched20.dll to native (needed for some dialog boxes and numbers on graphs to display properly). It is not necessary to install the dll, as Office installs its own version. Do not set this override globally unless you have Office installed in a separate wineprefix.

if you have issue in Excel 2007 opening in wine 1.7.4 you need to override it with riched20.dll native builtin, and after that all will work flawlessly
