Rename the library subdirectory in your new installation to something
like library.new.  Copy the library subdirectory in the old
distribution to the new installation.  Copy the contents of the
renamed library.new to the the directory copied from the old
distribution.  You should then start your new R and update packages
from the menu.  Check and ensure that you have not enabled automatic
loading of packages in /etc/Rprofile.site (eg to run Sciviews or
similar)  For further information see the Windows FAQ.
