Installing .84 over .83 doesn't work, you get some "file not founds" on the
Registar Command Prompt window during instaltion.
And when you start VS you get:
The Add-In 'Resharper for VS.NET, version220.127.116.11' failed to load or
caused an exception.
Error Message: ]]>
Pressing Yes on the dialog and then running a repair on R#, gets it to work
But this has happen for every version I can remember ( at least for the last
4 versions, althouhg the error number could have been diferent).
