cmdninst and commctrl error

I have a gateway running windows ME. I tried to download a driver for a new
epson printer. It kept stopping right at end of installation with cmdninst
error. Now when I reboot I get cmdninst. I close it (ignore does nothing) and
it says commctrl will now close. back to the blue screen. I was able to get
into safe mode. I tried the microsoft support method of disabling various
devices and I deleted everything epson in the add/delete programs area.
(except a printer utility that the computer won't let me delete). I still
come up to a blue screen. Nothing in device manager seems out of order. I
also tried renaming cmdninst and extracting another one from a cab file into
the system folder. That didn't work either. I have a recovery disk but not a
windows ME disk. Does anyone have any other ideas?

Boot to Safe Mode and use System Restore and roll your PC back to the
state it was in before you attempted to install the Epson driver.

I tried that too but the earliest restore date is after I tried to install
the printer.

Not really but... You say that you downloaded a driver for your (new?) Epson
printer - wasn't one supplied with the printer?

Are you sure that the one you downloaded is the correct (and latest) one for
WinMe. Although not specifically related to Epson printers/drivers, the
following KB article *may* point you towards the problem/solution :-

The supplied disk gave me an error so I called Epson and they had me download
one specifically for Me and that printer which is when the cmdninst thing
started. Ican't really even try to install anything at this point until I can
get rid of the cmdninst error as I'm in safe mode.

As your SR points (pre-install of printer) have gone (as per your reply to
Mike) you *might* still be able to run scanreg /restore and retrieve a
registry that is 'pre' the install (last 5 dates should be offered) :-

Start | Run and type "scanreg /restore" (no quotes and note the space
between the g and /)

Oh! and maybe ...   whilst you are in Safe Mode, take a look at Start |
Settings | Printers and see if any sign of the printer there, which you can
remove/delete. Also, take a look in Device Manager and look for any yellow
exclamation marks (bangs) and delete/remove them. Reboot and see if that
gets rid of the cmdninst error.

BTW - Sorry if a daft question, but...   You did remember to physically
disconnect the printer before trying to troubleshoot ?

Yes I disconnected the USB cable. I looked at scanreg  /restore (thanks for
the suggestion)but it takes me back a few years which might be when my son
crashed it with a virus so I guess I would use that as a last resort. I might
try to restore to the original error before I tried anything and see what I
can do. The weird thing is that there was never any problem in device manager
even though everyone says the answer should be there. The only printer in my
printer setting is something for adobe. Something for the epson does show up
in my misconfig--start up list though so I unchecked that . didn't help
though. I guess I'm just rusty at all this--I should have remembered to set a
restore point before I tried to add theprinter. Lesson learned I guess.

Years?   You should have had 5 'fairly recent' rb00x.cab filles offered, at
least one of which (hopefully) pre-dating your printer installation. Take a
look in the \windows\sysbckup folder to confirm.

But remember, these 5 files update each (power-up) day (FIFO) so the longer
you leave it, the less chance you'll have of getting a potentially 'good'
registry (and attendant files) back again.

You could also take a look at win.ini or system.ini with a text reader (e.g.
notepad) and see if there are any references to your printer which might be
causing the error report. If there is an orphaned line in one of the files,
scanreg /restore 'should' resolve it - subject to the constraints mentioned
above. There *may* even be a win.old or system.old file floating about that
'just' predates the printer installation which you could salvage.

But from this distance, I'm running out of ideas.

Good (Irish) luck

This suggests that for some reason the scanregw entry is no longer present
or at least no longer checked in MSConfig | Startup as otherwise the
registry is backed up automatically the first time that the PC is switched
on and booted each day. Not important now but something I feel you might
want to correct once you have solved your other problems.
