       I think I probably have a 32-bit version and not a 64-bit, 
because it works with 32-bit R but not 64-bit R.


       Is it feasible to have both installed in a way that allows the 
each version of R to select its own version of Java?  A comment on 
stackoverflow suggests that may not be easy 
(http://stackoverflow.com/questions/5272216/is-it-possible-to-install-both-32bit-and-64bit-java-on-windows-7). 



       Thanks,
       Spencer
