: Many users stop at version 7.62 because later updates (7.63+) often remove "offline telecoding" functionality, requiring an official PSA server connection for configuration changes.

However, if you own a 2019+ model (e.g., second-gen Peugeot 208 or new Citroën C3), do not bother – 7.58 will not communicate with the NEO architecture. You will need to move to DiagBox 9.12 or later.
