If you possess a legitimate license (a physical CmDongle or a purchased CmActLicense), obtaining the correct installer is a matter of maintenance, not piracy.
To download the CodeMeter Runtime Kit v6.40b, follow these steps:
Note: Ensure you're downloading software from the official source or a trusted repository to avoid malware or compromised versions.
If you're unable to find a direct download link or if the version you're looking for isn't readily available, consider contacting Wibu-Systems support directly for assistance.
The CodeMeter Runtime Kit v6.40b is a legacy version of the license management software developed by Wibu-Systems. While it was widely used for managing digital rights and software protection, particularly in industrial automation and CAD applications, it is now considered obsolete and poses significant security risks. Security Warning: Critical Vulnerabilities
Downloading and using version 6.40b is strongly discouraged due to severe security flaws identified in all versions prior to 7.10.
Remote Code Execution: Versions older than 7.10 are susceptible to attacks that could allow a remote attacker to execute malicious code on your system.
Privilege Escalation: Critical vulnerabilities (such as CVE-2020-14509 and CVE-2020-14519) allow attackers to alter license files or cause a denial-of-service (DoS) condition.
Obsolescence: Version 6.40b was released years ago; current versions, such as 8.40e (as of March 2026), include essential security patches and support for modern operating systems like Windows 11. Where to Find Official Downloads
For safety and compatibility, you should only download the CodeMeter Runtime Kit from official sources.
Latest Version: The most secure and up-to-date versions are available on the Wibu-Systems User Software page.
Legacy Support: If your software specifically requires an older version, contact your software vendor (e.g., Rockwell Automation or Siemens) directly to ensure you receive a verified and "clean" installer.
Third-Party Risks: Avoid "free download" sites (like Software Informer) for security tools, as these files may be tampered with or contain malware. Core Components of the Kit

The official CodeMeter Runtime Kit is a free software package provided by Wibu-Systems to enable the use of protected software on your computer. It includes the necessary drivers and management tools like the CodeMeter Control Center and WebAdmin. Official Downloads
While version 6.40b is an older release, it is strongly recommended to use the latest version to ensure security and compatibility with modern operating systems.
Latest Version: You can download the most recent stable release (currently v8.40e as of March 2026) directly from the Wibu-Systems User Software page.
Developer Versions: If you specifically need developer tools or merge modules, visit the Wibu-Systems Developer Downloads. Key Components Included The Runtime Kit installs several essential components:
CodeMeter Runtime Service: Manages your licenses, whether they are on a physical USB dongle, bound to your computer, or cloud-based.
CodeMeter Control Center: A desktop application used to view active licenses and enter activation codes.
CodeMeter WebAdmin: A browser-based interface for advanced configuration, such as setting up a license server or troubleshooting. Important Notes
Compatibility: Most software that requires CodeMeter will work with a newer version of the Runtime Kit than the one it was originally packaged with.
Uninstallation: If you need to perform a clean install, you can remove the existing kit via Programs and Features in the Windows Control Panel.
Security: Avoid downloading from unofficial third-party sites, as these may contain outdated or compromised files. Always use Wibu-Systems' official site. CodeMeter Runtime - Wibu-Systems

The CodeMeter Runtime Kit v6.40b is a specialized software package developed by Wibu-Systems designed to enable license management for protected applications. It serves as the bridge between software products and their required licenses, whether those licenses are stored on a physical hardware dongle (CmDongle), a software-based container (CmActLicense), or in the cloud. Key Components of the Runtime Kit
CodeMeter Runtime Service: The core background process (service or daemon) that manages active licenses, tracks usage, and connects to license servers across LAN, WAN, or cloud environments.
CodeMeter Control Center: A desktop utility that allows users to view connected dongles and manage computer-bound licenses, including an activation wizard for offline license updates.
CodeMeter WebAdmin: A browser-based interface for detailed overviews of available, activated, and test licenses across a network.
License Security: Provides a safe environment for code decryption, protecting software against piracy, reverse engineering, and tampering. Downloading and Installation
For security and stability, it is critical to download the Runtime Kit only from official or verified sources.
Official Downloads: Users can find the latest versions, such as v8.40e, directly on the Wibu-Systems Support Page.
Specific Versions: While v6.40b is an older release, it is sometimes required for legacy hardware or specific software compatibility. Developers often bundle the necessary version within their own product installers.
Platform Support: The runtime is available for multiple operating systems, including Windows (32/64-bit), Linux, and macOS. Why is it needed? Note : Ensure you're downloading software from the
Without this kit, applications protected by CodeMeter will fail to launch because they cannot verify the required cryptographic keys. It ensures that the right license is assigned even if an application crashes or a developer forgets to assign one manually. CodeMeter Runtime - Wibu-Systems
You can download the CodeMeter Runtime Kit v6.40b and other older versions directly from the official Wibu-Systems website. Official Download Sources Wibu-Systems User Software : The official User Software Download Page
includes a dedicated section for "No Longer Maintained Operating Systems" where legacy versions like are hosted. Archived Versions
: While the latest version is typically promoted, specific older releases are often available in the support archive. For v6.40b specifically, you may need to check the "CodeMeter - No Longer Maintained Operating Systems" list on the Support Center Alternative Support Portals : Partners like Rockwell Automation Graphisoft
also provide direct links to compatible CodeMeter drivers for their specific software versions. Important Notes for v6.40b Security Risk : Wibu-Systems warns that older versions (like v6.x) do
contain current security fixes and are no longer supported. It is highly recommended to use the latest version (currently v8.40e) unless a specific legacy application requires an older driver. Silent Installation
Assume you have obtained the file safely. Follow these steps to avoid "Error 37" or installation rollbacks.
A: Yes, CodeMeter Runtime exists for macOS (.dmg) and Linux (.deb or .rpm). However, "v640b" is primarily a Windows version. The Linux equivalent would be version 6.40 from the Wibu archive. For macOS, Apple's notarization requirements make v640b unusable on modern macOS.
When looking to download the CodeMeter Runtime Kit v6.40b or any software for that matter, it's crucial to exercise caution and follow best practices:
A: The official runtime is safe. It is a signed kernel driver from a reputable German security firm. However, cracked versions of software often bundle modified CodeMeter.exe files that are trojans. Always checksum your file.
Cause: v640b uses an older threading model that modern Windows security patches may time out. Fix:
Step 1: Run as Administrator
Right-click CodeMeterRuntimeKit-v640b.exe > Run as Administrator. User Account Control (UAC) will prompt you—click Yes.
Step 2: Language Selection Choose your language (English or German are most stable). Click OK.
Step 3: The Setup Wizard Click "Next." Read the license agreement. Wibu's license for runtime is free usage, but you must accept. Check "I accept..." > Next.
Step 4: Installation Type Select "Complete" (installs Control Center, Server, and WebAdmin). Do not select "Custom" unless you know you don't need the GUI.
Step 5: Driver Installation Warning Windows will warn: "Would you like to install this device software?" Click Install or Trust. This is the kernel driver for the USB dongle.
Step 6: The "v640b" Specific Step Unlike modern versions, v640b may require a system restart immediately. Do not postpone this. The service will not start correctly until after the reboot.
Step 7: Post-Reboot After reboot, plug in your USB dongle. Wait 10 seconds. Open CodeMeter Control Center from the Start Menu. You should see your dongle serial number under "Local Server."
