I have SQLite installed now (though, I don't think that matters... Bonobo comes with its own SQLite dlls. I AM running on a 64 bit system. I don't know if that has anything to do with compatability. I've followed the installation instructions on the Bonobo site to the tee, but I still get this error and Google hasn't provided any answers for me. Could anyone point me in the right direction?
