Try setting the TCL_LIBRARY environment variable to C:\Tcl\lib\tcl8.4. 
You may need to set TK_LIBRARY similarly.

IIRC, Windows versions of Tcl/Tk look for the library directory
relative to the location of the executable, which doesn't work if
you're using a custom program which uses the Tcl/Tk libraries rather
than the standard tclsh/wish programs.

Unix versions hard-code the default directory into the libraries, so
this problem doesn't arise.
