memory dump file not found in MikTeX 2.9

I recently installed  MikTeX 2.9 over MikTeX 2.7 (2.7 still
active, but in a different folder).

When I tried to run etex, I got the error

                   " etex: memory dump file not found "
                   " data: etex.fmt

Following instructions (from the "managing memory dump files"
page), I added `etex' in the `formats' button of the
`settings' menu; then `etex' showed up seemingly properly in
the `formats' list. I then ran `update formats' which,
however, produced the error

                  " miktex-makefmt: Unknown engine: etex "

What am I doing wrong??

PS: I installed MikTeX 2.9 for all users. in the above, I
     chose `settings' , not `settings(admin)' etc.. Is that
     perhaps the source of my problem ??

Any help appreciated.

ccn.
