Opens the file with Adobe Reader!
both open the file with SumatraPDF.

It seems to have the right variable values all the time, but when it
the pdf file just opens up with Adobe Reader. All the variables are
showing SumatraPDF as what to use.
I tried changing the viewer to just "SumatraPDF.exe"without the path for
both Sweave and AUCTeX, based on the experiment in the shell above, but
no joy. Just another wonderful feature of Windows I guess.
In desperation I resorted to an ugly hack which seems to have worked. I
commented out the line
in ess-swv.el and byte compiled the result. Now the pdf viewer is not
invoked, but that is fine for me. I just open the pdf file with
SumatraPDF before I use knitr and pdflatex.
Thanks for the advice on debugging, it meant I was able to find the code
which opened the pdf viewer.
