tcltk and Windo$e

I am running R1.6.2 under windo$e98. I have followed the instructions in the
Win port faq concerning tck, but when I try 'library(tcltk)', I get

Error in dyn.load(x, as.logical(local), as.logical(now)) : 
        unable to load shared library
"C:/PROGRA~1/R/RW1062/library/tcltk/libs/tcltk.dll":
  LoadLibrary failure:  One of the library files needed to run this
application cannot be found.
Error in library(tcltk) : .First.lib failed

Any ideas?
Thanks
Karen
