According to ?bugs:


bugs.directory: directory that contains the WinBUGS executable. If the 
global option R2WinBUGS.bugs.directory is not NULL, it will be used as 
the default.

working.directory: sets working directory during execution of this 
function; WinBUGS' in- and output will be stored in this directory; if 
NULL, a temporary working directory via tempdir is used.

So either specify working.directory in a way that it points to the 
model.txt file or specify a full path name for your model.file

I don't believe that bugs.directory="E:/Rprograms" will do anything 
sensible (as it should point to your WinBUGS installation.
