DiagBox initially followed the ISO 639-1 (2 Chr$) language standard (Example EN for English). From DiagBox v7.74 on, Actia released DiagBox with ISO 639-1 (Language) followed by underscore and ISO 3166-1 (Country code/Locale), ie.. en_US or en_GB (5 chr$).

Because DiagBox was patched in the first release, some files from earlier releases still exist in new compilations. Some of those files are now replaced with newer versions that look for 5 chr$ codes and not 2 Chr$ codes causing the (patched) system not to work properly...

It is possible to make DiagBox 7.74+ work with 5 Chr$ properly, but it takes a lot of testing time and effort; since those who wrote the software did not provide documentation with it.

However, I have compiled a genuine PSA DiagBox 7.66-7.72 update; (the latest ISO 639-1 version that works with 2 Chr$), it is mainly an update to Lexia and PP2000 and will upgrade your DiagBox v7.66 system to the following versions:

DiagBox=7.72 Firmware=4.3.3 Lexia=500.69 PP2000=600.73

This is for educational and experimental use, and I hold no responsibility for any improper usage or damage to your system..

Update process:
1- Download "DiagBox_766-772.exe" (69mb) and reboot your computer and do NOT start DiagBox.
2- Navigate to C:\AWRoot\bin\fi\ and create backup copies of your "cache" folder and "Appdiag.sys" and "cfg.bin" files; (precaution).
3- Run "DiagBox_766-772.exe". Click on "Extract" and When finished restart your computer.
4- Run your DiagBox and it will perform the update.

I could have automated the whole process and made it look like black magic; but it is not, and would defeat the whole purpose of sharing. It is "Simple"

Once again, I am not in this business, I do it for love not for a living, and I don't mind people sharing it (with reference).

I tried to update version 7.65 and have a message that update NOT performed.

Should I use other version of Diagbox ? Any advices ?

Yes, it is from 7.76 not 7.65. So, use Maitresox's 7.62-7.66 to bring your installation to 7.66, then it should work.

To check, I have created another Windows XP system and updated from Scary's 7.65 to 7.66 (using genuine PSA inter7_66 update). I then used 7.66-7.72, the upgrade went smoothly and was successful.

Please notice that the "Appli, MAJDIST, Reco and majdist.tmp" all need to be directly in the "C:\AWRoot\dtwr\updt" folder, like this:
"C:\AWRoot\dtwr\updt\majdist.tmp" and this "C:\AWRoot\dtwr\updt\Appli\" ... etc..

Thanks Joe2, you will notice that I learnt from your feedback and updated the process in the first post..
