The old 1.61 loader only supports R < 2.12. You'll need the new loader (1.62) for R 2.12.0 (now as jgr-1_62.exe on RForge). Also if you want to use the 64-bit version of the loader (jgr-1_62-x64.exe) then you will need the latest rJava 0.8-8 binary from RForge as well.

That sounds like an old JavaGD binary without 64-bit support - make sure you install the latest JavaGD binary.

That said, Deducer crashes R when used in the 64-bit GUI so you may want to stick to JGR if you want to use 64-bit.

Cheers,
