Or better ask, is the an 64-bit version of R? I only know of one
commercial beta release ...
If so, is this an rJava version made for this version of R? Does any
Windows error message appear on your screen?

Did you verify that all your apps/libraries are all 64-bit compatible?
If your dll indeed exists in the directory it complains about, I would
venture that it's a mismatch between 32-bit and 64-bit libraries (R,
rJava, Java).

Subject: [R] Problem with loading rJava in R
Hello.
I am trying to load the rJava package in R-2.7.2 (Windows XP 64-bit
RGui)
and get the following error message even though the mentioned .dll file
is
located at the directory listed in the error message. I have tried to
uninstall and reinstall the package but that does not resolve the
problem.
Then uninstallation and re-installation of R did not resolve the issue
either. Any suggestions are appreciated. charis.
