Problem with namespace installing rJava

Question

I am installing rJava on a 64bit machine, running Windows XP, and am encountering the weirdest message. Below is the log. Has anyone seen this before? Thanks in advance.

 > install.packages("rJava")

Answer 1

Looks like a garden-variety binary incompatibility to me.

The NAMESPACE is a red herring as it happens to load the dynamic library, and that's where the trouble lies.

Answer 2

Does the DLL file exist at that path? If it does, than maybe it's one of its dependencies that's missing. Try http://www.dependencywalker.com/ to identify which one.

After that...?
