    I'm using R2jags and rjags version 2.1.1 installed, in this instance on
    Windows XP, but get this error when trying to run a model. Any suggestions
    about how to get it to find and use the correct version?

    R version 2.11.1 (2010-05-31)

    I think so, at a command prompt I get

    $ jags

    The rjags package is supposed to pick up the location of the JAGS installation
    from the Windows registry, since the installer will write the install location
    there. If this fails, you can set the environment variable JAGS_HOME before
    loading the rjags package.

    PS You say you are working on Windows XP but your example has a unix prompt.
    What's going on there?

    Thanks for the advice for environment variable, in fact this is the only
    working solution I can found online!

    I have exact the same problem. I installed both JAGS 2.2.0-win64 and R 2.12.1,
    system is win 7 64bit.

    BTW: The installation manual is quite misleading. It is more about compile the
    executable than the actual installation.
