Why would someone still want V8.0 in 2026?
The Critical Warning: Siemens has removed direct links to V8.0 from their main “Downloads” page to push users to newer software. You will find it in the “Archive” section. If a website promises a “free unlocked full version” of V8.0 – it is either a trial (which requires a license key) or dangerous software.

Installation Tip: Disable anti-virus temporarily only if you trust the source (Siemens). Some security suites flag Siemens’ license manager as a false positive.
What if the download fails? Use Siemens Automation License Manager (installed alongside the software) to test licenses. For missing downloads, contact Siemens support with the exact MLFB number of your LOGO! module.
After downloading the installer, run it as administrator. The installation wizard guides you through accepting the license agreement, selecting components (e.g., help files, examples), and choosing an installation directory. Once installed, launch the software. You will be prompted to enter a license key or start a trial. Licenses are tied to a Siemens ID or a physical USB dongle (depending on purchase model). For educational or hobby use, Siemens offers time-limited trial licenses that can be renewed.
