Hi Ben, After a reboot I got it to work this morning. I really thought that a new process (launched from eclipse) would grab the updated PATH environment variable but apparently not. I'm still wondering exactly what tripped me but as long as it now works... Thanks.

I will try on a virtual XP box next. Can you include the stacktrace you are seeing when you run the workflow with the R expression? The actual workflow might also help me track down any problems.
