I really appreciate all your help but I've already tried everything that has been suggested.
I changed the path to every possible combination that leads to an R executable...and nothing seems to work. I've checked to see that Im typing it right. I've also asked my sister to make sure (a fresh set of eyes is always helpful). The only thing that work are navigating to the folder holding the R executable (R_HOME/bin) and the batchscripts. However, this doesnt help me in working with rpy2.
