I've just been informed that AutelTech has finally published an update package for the MS409 on their web
site. I've just installed Program Update Ver. 2.00 (MS409.dag) and DTC Update
Ver. 2.60 (AT45DB161.AUT) on my MS409. The display is ok and the scanner is
functioning normally so this is a good update. The above link points to a zip
file containing these new updates and a copy of
MaxiLink ver. 1.08, which I've
used with WinXP and Win7 without problems. There was a bug in the older MaxiLink
version supplied with the MS409 scanner that would cause garbled text on the
display when used with Win7 to install the DTC update. Version 1.08 does not
have this bug. Here are
update packages for the
the MS609 and
AL519 scanners if
you found this page looking for updates for these scanner models.

This info was sent to me recently with a request to post it here in the hopes that it may help some of you.
The MaxiScan MS409
and the Cen-Tech 99722 are essentially the same unit so the current MS409 update
"Updating the ".dag" file is intuitive. Updating the ".aut" file requires the user to press the left arrow button until the device reads "communicating with pc." The software says to hit the enter button, but that is inaccurate."
Thank you for this info, Erik. ;-)
