How about this one, interesting.. I updated my rapid version and R plug-in and it redid the installation process and found the libraries and all seemingly OK. As I click the exit restart button, it never restarts.. fine no problem i restart it myself only to wind up back in the R plugin installation process again... Can't get out!!

    I get a bit further before the loop starts.  When I click NEXT, I get

    Found Library in C:\Program Files\R\R-\library\r.Java\jri\JRIEngine.jar  This is a good thing.  I can click OK to get to the EXIT now, I will restart RapidMIner.  That's when the loop starts.  Interestingly, If I click the upper right hand corner X to exit the dialogue box, I do go to RapidMiner, but then get this error:

    Could not load native library The local binary library 'C:\Program Files\R\R-\library\r.Java\jri\JRIEngine.jar' could not be loaded
    Reason: C:\Program Files\R\R-\library\r.Java\jri\JRIEngine.jar %1 is not a valid WIN32 application.

    This is odd, as I only downloaded the WIN32 files and not any WIN 64 files.

    I can still run the application, but not the R operator.

    I uninstalled all, re-downloaded all files to make sure that all were WIN 32 and got the same results.

    well, I will add a Button do deactivate the extension if you can't get it to work. Until then, please press the X button of the dialog and deactivate the Extension in the Help / Manage Extensions Menu.

    Please install R 2.12.0, since I don't have tried it with 2.12.2. Then please check if the jri.dll in the C:\Program Files\R\R-\library\rJava\jri\ directory is indeed a copy of the C:\Program Files\R\R-\library\r.Java\jri\i386\jri.dll

    I have the exact same problem cidiel has.. I just installes R and was looking forward to using it.. so I install R and everything seems OK, until I get into the same loop of death.. and when instead of clicking the "exit restart" button I press the x button RapidMiner opens and tells me he could not find the respective jri.dll.. So how come he found it during the installation, or at least made me believe..

    we will make another update as soon as possible cutting this loop and we are heading for including the complete R into the Extension, so that any inconvenient configuration will be avoided.

    I had also encountered this problem and I have found the solution. I have posted my original question and the solution at the following post


    In essence, using something like


    in  .bashrc worked out for me.
    If it does not work, i.e if lib.so is missing, try follow the instructions at the URL

    It looks like it is more of an R problem than that of rapidminer.
