Even with valid licenses, some S7 program blocks may be password-protected. EKB Install does not crack block passwords. Use S7BlockPasswordTool (another separate utility) – but that is outside this article’s scope.

As of 2026, SIMATIC EKB Install 2013 is obsolete for most current tasks because:
However, it may still be found in legacy maintenance environments (e.g., plants running Step 7 V5.5 + Windows 7), but even there, using it is risky and illegal.
SIMATIC EKB Install 2013 remains a remarkably resilient and useful tool in the automation engineer’s utility belt. While it is not sanctioned by Siemens, its ability to resurrect legacy systems, enable training environments, and bypass dongle headaches has earned it a legendary status in industrial forums.
That said, always weigh the risks. For any system that controls real machinery – conveyors, robots, chemical reactors, or power grids – do not rely on cracked licenses. The cost of a genuine Siemens license is negligible compared to a production shutdown caused by license checker triggers or legal liability.
For home lab users, students, and legacy system caretakers, EKB Install 2013 is a safe, effective, and well-documented solution – provided you follow the steps carefully and keep the tool offline. simatic ekb install 2013

The following article is written for informational and educational purposes regarding the historical software utility known as SIMATIC EKB Install (2013).
Understanding SIMATIC EKB Install 2013: A Historical Overview
In the world of industrial automation, Siemens SIMATIC TIA Portal and Step 7 are the industry standards for programming PLCs (Programmable Logic Controllers). However, the high cost of licensing has led to the emergence of various community-driven tools over the decades. One of the most discussed legacy tools in automation forums is SIMATIC EKB Install 2013. What is SIMATIC EKB Install?
SIMATIC EKB (Electronic Key Buddy) Install is a third-party utility designed to manage and "unlock" license keys for Siemens automation software. The 2013 version was specifically tailored to handle the licensing requirements of software released during that era, including: SIMATIC Step 7 v5.5 TIA Portal v11 and v12 WinCC Flexible SIMATIC S7-PLCSIM How the Tool Functioned
The utility worked by generating "ShortKeys" or "LongKeys" that mimicked the official Siemens ALM (Automation License Manager) keys. Users would typically follow these steps: Even with valid licenses, some S7 program blocks
Selection: Users chose the specific software version from a tree menu.
Installation: The tool placed a virtual license file into the hidden "AX NF ZZ" folder on the C: drive.
Validation: The Siemens Automation License Manager would then recognize these files as valid keys, allowing the software to run without trial restrictions. Technical Specifications of the 2013 Version
The 2013 release was a milestone because it bridged the gap between the classic Step 7 environment and the then-new TIA Portal framework. Key features included:
Compatibility: Support for Windows XP and Windows 7 (32-bit and 64-bit).
Database Updates: Included a wider range of EKB codes for specialized industrial modules.
Search Function: Allowed users to search for specific missing licenses by their internal Siemens ID. Risks and Ethical Considerations
While SIMATIC EKB Install 2013 remains a popular topic for students and hobbyists practicing PLC programming at home, it carries significant risks: 1. Legal and Compliance Risks SIMATIC EKB Install 2013 typically includes:
Using EKB tools in a commercial or industrial environment is a violation of Siemens' End User License Agreement (EULA). Companies found using unlicensed software can face massive fines and legal action during audits. 2. Operational Stability
Automation software is used to control heavy machinery. Unofficial license "cracks" can sometimes cause the Automation License Manager to crash, leading to unexpected downtime or loss of communication with the PLC—which can be dangerous in a live factory setting. 3. Malware and Security
Since EKB tools are distributed through unofficial channels and "underground" forums, they are frequently bundled with malware, trojans, or miners. Always exercise extreme caution when handling executables from unverified sources. The Modern Alternative: Siemens Trial Licenses
Today, Siemens provides much safer ways to learn their ecosystem. They offer 21-day Trial Licenses for almost all TIA Portal versions. For students, many universities provide legitimate educational licenses through the Siemens SCE (Siemens Cooperates with Education) program.

Which version of Step 7 or TIA Portal are you currently trying to learn?
I notice you're asking about "SIMATIC EKB Install 2013." This is a tool reportedly used to generate or install "know-how protection" keys and licenses for Siemens SIMATIC automation software (like Step 7, WinCC, etc.).

Bottom line: I can’t provide a download, instructions, or endorse using SIMATIC EKB Install 2013. If you’re facing licensing issues with Siemens software, I’d be happy to help you find legitimate, safe solutions instead.
