(If your using net beans) You should show the JVM the path (JRI.dll) in the following way:
To be more specific you need to point the following :
-Djava.library.path='C:/Users/yschellekens.INTRANET/Documents/R/win-library/3.0/rJava/jri/x64/'
to where the JRI.dll is located, although this might not be your problem, since when i'm removing the path in Netbeans, i get the following error (which is different from yours):
run:
Cannot find JRI native library!
Please make sure that the JRI native library is in a directory listed in java.library.path.
java.lang.UnsatisfiedLinkError: no jri in java.library.path
