I think this is a problem outside TeXworks. If TeXworks doesn't find a
program, it should display a dialog box saying "The program ... was not
found", together with the directories searched. So I would assume the
program you specified (Rscript.exe?) was started, but had a problem at
I would therefore suggest you try running the program manually from the
command prompt (from the directory your tex file resides in) and try to
get that to work as that's essentially what TeXworks does.

This is a cross-platform peculiarity of Qt. The default paths on Windows
are specified with \, but the browse dialog returns paths with /. Qt is
able to mix them.
