No problems will arise because of the different word size.

You will possibly see problems if you have the two versions set up to 
use different libraries; occasionally a workspace will fail to load if 
it needs a package that is not installed.  Normally on WIndows the same 
library can be used for both 32 and 64 bit R, but you could always 
choose to break that.
