Please make sure that your Java architecture matches your R architecture and then re-install the matching Java (i.e. both have to be 32-bit or both have to be 64-bit - you cannot mix/match). It seems that there is a problem with your Java registry entries. The version is irrelevant - any Java version 1.4 or higher should work.

Please direct further questions to the stats-rosuda-devel mailing list for rJava.

Thanks,
