It looks to me like the Autel MS409 appears to be a twin brother to a Cen-Tech 99722. You check tool information on the screen of your Cen-Tech 99722 see what the version of software, LIB version etc is at . Download the MS 409 zip file, un zip and see what the software version and LIB version of that is compared to what is on your equivalent looking Cen-Tech 99722 before trying anything.
