I am not sure, if this is the right forum for my issue. Please let me know if not and will try it in another one.
Since it seems to be amazing extension, I am trying to run Rapid Miner's R-Extension. Without any success for over a day now. I don't know how to help myself anymore, that's why I decided to write this post.
After starting Rapid Miner I get the error message:
Could not load native library.
R Extension could not be initialized. Error while loading native R library. Please check PATH,R_HOME and JAVA_HOME environment variables settings.Reason: 'C:\Program Files\R\R-3.0.1\library\rJava\jri\x64\jri.dll: Can't find dependent libraries'

! But: It is possible to load rJava (version: rJava_0.9-4) into a R-workspace. Tried out with RStudio.
That's it! I don't know, what to do anymore to get out of this situation. As you can see, I read all posts in stackoverflow with the same issue. But nothing helped so far. Is there anything I did not consider?
I appreciate each help very much. If there any things you need to know for further steps please let me know.
Thanks in advance,
Rudi
If you change JAVA_HOME so that it points to the Java run time environment, does that help?
In other words, put /jre at the end.
