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.

[null] Cannot find JRI native library!
     [null] Please make sure that the JRI native library is in a directory

d in java.library.path.

and Ben responded:
2. The RExpression2 (JRI-based) actor will fail if the libs are not found. This
is probably deep in the JRI.jar library when it cannot load the correct native
lib for the platform. We could probably try to detect the 32 v. 64 bitness of
the system and prevent the actor from attempting to use JRI if it was on a 64
bit machine - otherwise it will be the hard failure (system.exit)

and Jianwu:
Matlab actors also have 32 and 64 bit issue when using JNI libraries to
communicate with Matlab. It will pop up an exception message when the JNI lib
doesn't work with the system. You can find some information at
https://kepler-project.org/developers/teams/build/matlab-lib-build-instructions-in-kepler-for-matlab-actor.
It may help this bug.
