Tkinter importing error

[Costas Menico]

Does anyone know why I get the following message when I try to import
Tkinter on Windows 98?

>>> import Tkinter
Traceback (innermost last):
  File "<interactive input>", line 1, in ?
  File "d:\python20\lib\lib-tk\Tkinter.py", line 34, in ?
    import FixTk # Attempt to configure Tcl/Tk without requiring PATH
  File "d:\python20\lib\lib-tk\FixTk.py", line 1, in ?
    import sys, os, _tkinter
ImportError: DLL load failed: One of the library files needed to run
this application cannot be found.
>>> 

Where is Tk supposed to be installed? The Python I use is
ActiveState's version.  Thanks
