Legacy versions of PP2000 and Lexia are notoriously sensitive to modern operating systems.
Modern PSA diagnostic setups rely on Diagbox, which acts as an overarching front-end wrapper. While newer versions of Diagbox contain sub-routines for older vehicles, they often fail to communicate properly with k-line protocols or early CAN-bus systems used in the late 1990s and 2000s.

Original for electrical isolation.
If you have ever typed the keyword into a search engine, you already know the struggle. You are looking for a specific, stable, uncorrupted version of software that works flawlessly with older hardware interfaces (like the Full Chip or Rev. C interfaces) without forced updates, telemetry, or feature degradation.
Thanks everyone. I found a stable dual boot setup. If anyone needs help installing without Diagbox interference, let me know. I’ll write a short guide in the tutorials section. Legacy versions of PP2000 and Lexia are notoriously
Ensure you are using the correct offline activation process.
While PP2000 was Peugeot's platform, served as Citroën's equivalent system, also developed around the late 1990s to early 2000s. Lexia offers identical deep-level access to a vehicle's electronic systems, including detailed troubleshooting, component activation (such as suspension hydraulics and airbags), and software updates for ECUs.
