You appear to have downloaded the wrong copy, despite rather clear 
instructions on that site. To wit,

To install on *R v1.9.1 or earlier on Windows*, call

install.packages("R.classes", contriburl="http://www.maths.lth.se/help/R/R190")

Although it also says

Since the Windows is a binary distribution written in 100% R it can also 
installed by extracting the archive files into the library/ directory of 
your R installation, i.e. ${R_HOME}/library/ such that the directories 
library/R.oo/, library/R.graphics/ etc are created.

which is incorrect as the `100% R' is transformed in version-specific ways 
(and one does hope it has help files ...).
