Hi Thomas,Thanks again. I'll try to scrub everything and re-install. In the meantime, here is what I have found.
i)> Try starting RKWard from
the command line as C:\RKWard\KDE\bin\rkward.exe --R C:\RKWard\R\bin\i386\R.exe
Each of the 'segments' works on its own (i.e. R.exe starts R). Together, the usual 'backend' error comes up. ii) Nothing happens in the RWard R Console window which I assume means no R running. iii) Running R (from CMD) and your suggested commands shows, among other things that .libPaths() is looking for the D: (optical on my machine) drive (the shortcut to RKWard.exe also tries to open RKWard.exe in D:). I'm attaching a screenshot of the cmd window since I can't remember how to extract the text.

I believe the problem is a left-over from the previous attempt, somehow, adn RKWard tries to use a wrong installation of R. Try starting RKWard from the command line as C:\RKWard\KDE\bin\rkward.exe --R C:\RKWard\R\bin\i386\R.exe If this does not work, we'll have to proceed with some more diagnostics: 1) I believe (but I'm not sure) that simple commands should work in RKWard's R Console Window at this point. Please try sessionInfo() and .libPaths() and paste the output. 2) Whether or not the above worked, start up R at the new installation path (C:\RKWard\R\bin\i386\R.exe as far as I understand), and try running sessionInfo() .libPaths() and library("rkward") 3) Double check that the folders C:\RKWard\R\library and C:\RKward\R\library\rkward exist. Otherwise, clear C:\RKWard, completely, and try unpacking from fresh. 3b) Clearing C:\RKWard, and unpacking from fresh might be a good idea in any case. 4) My best idea at this point is that R is somehow mislead into using a wrong library location. Please double check that no .RPprofile file is trying to override library paths in your user directory. Either move .RProfile out of the way, or modify calls to .libPaths() to include the original paths (as in .libPaths() <- c ("My\Own\stuff", .libPaths()) I hope one of the above will finally get us somewhere. Thanks for your patience! Thomas
