You have installed WinBUGS there? A very unusual location for a software 
installation. Anyway, use the argument "bugs.directory" as ?bugs 
suggests to set the directory where WinBUGS lives.

You may want to switch to a more recent version for controlling BUGS 
sampling, e.g. the BRugs package that does it more "integrated" into R 
or R2OpenBUGS as the OpenBUGS interface.
