APPDIAG.SYS diagbox 7.01 patch

Unread post by Joemoonlit »

Hi,
I just bought a Lexia 3 Diagbox 7.83 Full Chip tool including the software in order to diagnose a fault on my Citroen Xsara Forte.
The actual tool looks OK, but when I have installed the software they provided an installation password Scary01 in order to activate it. I have input that and it has failed activation. The computer is not connected to the Internet and I am using Windows 7 professional. I had to instal a virtual CD and install the software to that as advised by the supplier.

Currently the software shows 7.01 but it is not activated. I have read that I need an APDIAG.SYS diagbox 7.01 patch file which if I copy to C:\AWRoot\bin\fi\ then this should fix the activation.
Would anyone have a copy of such a file they could share?

Regards Ian

I'll install Lexia on another laptop one of these days, and I'll send you the file (if I remember to save it before I proceed with the upgrade :mrgreen:).

Some things don't fit.
The APDIAG.SYS location C:\AWRoot\bin\fi\ can only be copied and used from your own PC, because it contains the data of the hard disk and the software version.
If you change the software version or the hard drive, the APDIAG.SYS can no longer be used.
Whether the APDIAG.SYS is saved with 7.01 or better with 7.02 is not important.
However, 7.01 cannot be used for diagnosis and only when this is completed by the automatic installation of 7.02 can a diagnosis be started or further updates be possible.
Updates higher than 7.57 or 7.62 are very rarely useful and should be omitted for vehicles up to the beginning of 2015.
