To summarize the Schneider SoMachine V4.3 download landscape:
SoMachine V4.3 was a brilliant piece of engineering in its day. But remember: In industrial automation, the cost of a PLC is trivial compared to the cost of downtime. Using legacy software requires legacy discipline. Secure your download safely, keep your license dongle in a safe, and always test your code on a bench PLC before going to production.

Report: Schneider Electric SoMachine V4.3 Software Availability and Acquisition
Date: October 26, 2023 Subject: Acquisition and Download Procedures for Schneider SoMachine V4.3
This is the biggest hurdle for end-users. If you cannot legally download V4.3, you have two options:
Since you are here for the download, you are likely stuck in the past. But let's talk about the future to save you time.
EcoStruxure Machine Expert (Machine Expert V1.2 and V2.0) is the direct successor. It looks and feels 95% like SoMachine V4.3 because it is also built on Codesys V3.5.
The Migration Path:
Is there a price for V4.3? Technically, you cannot buy a new license for V4.3 today. If you own a license for Machine Expert, it includes downgrade rights to V4.3. If you are a home user/hobbyist – be aware that Schneider does not offer a free "Trial" for V4.3 anymore; you must use Machine Expert Trial.
