note:
what is needed is to have a JRE installed that is the same number of 
bits as the browser. a 64-bit JRE will not work with a 32-bit browser 
and vice-versa. this is generally a result of how most browsers handle 
plugins.

AFAICT, one can have both a 32-bit and 64-bit JRE installed at the same 
time on the same system and this seems to work (although I have not 
entirely investigated the details of this).


another option is to install a 64-bit browser, but at least in the past, 
this had problems with Flash player (lack of 64-bit Flash players, 
although last I remember there was a Beta-stage 64-bit version of Flash 
available, and it may be in release status now for all I know...).
