[Simple]

For the technically oriented:
Below is a link for the complete "C:\APP" folder for DiagBox version 8.19 (includes Lexia and PP2000) already updated (838MB).. it does not include the DiagBox 8.19 "C:\AWRoot" which has the Profile Configuration files, but it should work with your current "C:\AWRoot", and the reported version number on your computer will NOT be changed. It might require the installation of VC++ 2008..

If you notice any operational difference; share the experience.

Try at your own risk...

To try it:
1- Kill all DiagBox services (including sim and FireBird)
2- Rename your current "C:\APP" folder to "C:\APP7"
3- Extract (Here) the App819 to the "C:\" drive and you should have "C:\APP" (make sure you don't have another APP folder inside C:\App\)
4- Restart the computer and try the complete DiagBox 8.19 Engines..

To revert:
1- Just kill all services (including sim and FireBird).
2- Rename the "C:\App" folder to "C:\APP819"
3- Rename "C:\APP7" to "C:\APP"
4- Restart the computer and run DiagBox,
5- If all is well, delete "C:\APP819" or keep it to try whatever you wish at a later stage..
