I found two workflows can not be executed on Windows 7 64 bit:
Kepler-2.0.0-Demos\demos\R\r-2.0.0\demos\R\localFile_to_dataFrame_R and
sampling_occurrenceData_ R.

First of all, many workflows still use property("KEPLER") which should be
changed to property("DEMODIR").

For workflow "sampling_occurrenceData_ R", it tried to use
property("KEPLER")+"/lib/testdata/garp/DataPoints.txt". I finally found the
file at Kepler-2.0.0-Demos\demos\R\data\garp directory. So it probably should
be property("DEMODIR")+"/data/garp/DataPoints.txt"

After I manually pointed to the correct dir, these two workflows work for me.

I also tried workflows in Kepler-2.0.0-Demos\demos\R\r-2.0.0\demos\JRI
directory, the whole Kepler just quit with the following message in the
console. It makes sense that the dll doesn't work for 64 bit machine. But just
quitting Kepler is too unfriendly.

P.S.: Do the workflows in Kepler-2.0.0-Demos\demos\R\r-2.0.0\demos\JRI\problems
directory really have execution "problems"? This directory name is confusing.
