memory dump file in MikTex 2.9

I have just changed from MikTeX 2.7 to MikTex 2.9 . Most
things work smoothly, except:

when using etex, e.g.  " etex.exe source.tex " ,
I get the error message

                  " etex: The memory dump file could not be found
                    etex: data: etex.fmt                          "

I think I understand what that means: googling `managing
memory dump files' gave some good info. But I am still not
quite sure what exactly I should do in the `MikTeX Options:
general settings' window (as recommended there):
         just add etex.fmt ?
             in admin mode ?

I would appreciate any practical advice; thanks.

ccn.
