not that I know of, and it works fine on my WindowsXP. This answer in the R windows FAQ seems to indicate that it's a known, but not really understood problem in R: http://cran.r-project.org/bin/windows/base/rw-FAQ.html#The-Internet-download- functions-fail_002e I don't know whether there is any sensible way for us to work around this.

There can be an arbitrary number of independent R installations on one system, and these do not even need to be in the registry. RKWard needs to know which one to use. The "config file" for that is rkward.bat itself. Modifying the location of the R-executable, there, would have done the trick in your case. Currently RKWard 0.5.4 compiled with any version of R between 2.9.x and 2.12.x should work with any of these versions of R at runtime. But sometimes there are incompatibilities, and for instance RKWard 0.5.4 compiled with R 2.8.x cannot be used with R 2.9.x or above. Also, quite often, you need the latest version of RKWard in order to run the latest version of R. For instance, RKWard 0.5.3 cannot run any user command in the R Console with R >= 2.12.x. So, I think the only safe assumption is that for a new installation of R, you will have to install the most recent version of RKWard. I don't see a good way to improve on that situation. One thing that we *can* improve is the case that the old R installation no longer exists. We'd simply need a check for that in rkward.bat, and then display a helpful message. Any volunteer for some Windows batchfile scripting? Regards Thomas
