Hi Phil:

Well, I was not able to see the attachment (tbird shows that there is a 
MIME part there, but it wouldn't let me open it).  It's just as well
since I don't have a Windows machine handy to try it on.  But, here's
my take on the registry.  It is fragile.  Somebody may have moved the
R executable.  Something that we do all the time on Unix and Mac, so I
suspect it is common on Windows as well.  And, the executables are fine
thereafter, however, I suspect the registry will be wrong then.  Is my
supposition correct?
