Since upgrading to 2.12.0, I'm having trouble getting the JGR to start under Windows 7, but I'm not quite sure what's happening.  

When I try to run the JGR.exe stub, the dialog says can't find Java R interface jri.dll.  As nearly as I can tell from a Google search this is to be a part of the rJava package which seems to load fine with the library(rJava) command from the Windows R GUI.  Indeed the required .dll is sitting in C:\R\R-2.12.0\library\rJava\jri as expected.  I must admit that my understanding of Java stubs is limited, and I don't know why this stopped working with the upgrade.

My ultimate goal of was to run the Deducer package which ironically runs fine from the Windows GUI despite recommending that I use JGR instead.  Any hints how I recover the use of JGR?

Thanks,

Rob
