Troubleshooting Guide: "A Valid AccuMark License Was Not Found For This Product" If you are a fashion professional or a pattern maker using Gerber Technology’s software, seeing the error "A valid AccuMark license was not found for this product" can bring your entire production line to a screeching halt. This error typically occurs when the AccuMark software is unable to communicate with the license key (dongle) or the network license server. Below is a comprehensive guide to identifying the cause and getting your CAD system back online. 1. Check the Hardware (Physical Dongle) If you use a physical USB security key (often called a "dongle"), this is the most common point of failure. Re-plug the device: Unplug the USB key, wait five seconds, and plug it into a different USB port. Check the light: Most Gerber dongles have a small LED light. If the light is off, the port may not be providing power, or the dongle itself may be defective. Avoid USB Hubs: Always plug your license key directly into the computer. USB hubs can sometimes cause communication drops. 2. Verify the Sentinel LDK License Manager AccuMark relies on the Sentinel LDK License Manager service to verify your credentials. If this service stops running, the software won't "see" the license. Press Windows Key + R , type services.msc , and hit Enter. Locate Sentinel LDK License Manager in the list. Check its status. If it isn't "Running," right-click it and select Start . If it is already running, right-click and select Restart . 3. Network License Issues If your office uses a floating or network license (where one server hosts licenses for multiple computers), the issue is likely a connection error. Check your VPN: If you are working from home, ensure your VPN is active. Without it, your computer cannot reach the office license server. Server IP Address: Open your web browser and type http://localhost:1947 . This opens the Sentinel Admin Control Center . Click on "Configuration" and then "Access to Remote License Managers" to ensure the server’s IP address is correctly listed. 4. Version Mismatch Gerber AccuMark licenses are version-specific. If you recently updated your software to a newer version (e.g., moving from v12 to v15) but did not update your license file or "re-burn" your dongle, you will receive this error. Check your contract: Ensure your subscription or maintenance agreement covers the version you are trying to run. Apply the .v2c file: If Gerber sent you a new license file (usually a .v2c extension), you must apply it through the Sentinel Admin Control Center or the Gerber License Update utility. 5. Antivirus and Firewall Interference Sometimes, aggressive security software blocks the communication between AccuMark and the license service. Temporarily disable your firewall to see if the error persists. Add an "Exclusion" or "Exception" in your antivirus for the AccuMark installation folder and the Sentinel LDK folder (usually found in C:\Program Files (x86)\Common Files\Aladdin Shared ). 6. Driver Reinstallation If the drivers for the security key are corrupted, a clean install is necessary. Go to the Gerber Technology website or the AccuMark Installation thumb drive . Look for the Sentinel_LDK_Run-time_setup or HASP User Setup . Run the installer to repair or reinstall the drivers. When to Contact Support If you have tried the steps above and still see the "Valid license not found" message, your security key may be physically damaged or your subscription may have expired. At this point, you should contact Gerber Technology Support with your Key ID number ready. Are you using a local USB key or a network-based license for your team?

"A valid AccuMark license was not found for this product" typically occurs when the Gerber AccuMark software cannot communicate with your security key (dongle) or the license management service. Keenfinity Knowledge Base 1. Check Your Physical Hardware (Dongle) If you are using a perpetual license with a USB hardware key: Reconnect the Dongle : Unplug the USB key and plug it back into a different port directly on the computer (avoid USB hubs). Check the Indicator Light : Ensure the light on the USB key is illuminated. If it is dark, the key may be faulty or the port may not be providing power. Verify Version Compatibility : Beginning with AccuMark Version 10, a new style of security key is required. Older keys (like those for V8 or V9) will not work with V10 or higher without a physical replacement or a specific update file. Ridom GmbH 2. Manage Your License File If you have a file-based or standalone license, it must be properly installed in the GT License Manager Locate the Installer C:\Program Files\Common Files\Gerber Technology\GT License Manager\InstallLic.exe Install the InstallLic.exe as the product type, and browse to your provided license file. Verify the Key Number : The license file number must exactly match the security key number attached to the computer. 3. Troubleshoot Drivers and Services The software relies on the Sentinel Runtime (HASP drivers) to detect the license: Restart Licensing Services Right-click the button and select Computer Management Sentinel LDK related services and click Repair Drivers : If the key is still not detected, run the Sentinel System Driver Installer and select the option to fix corrupted driver files. 4. Network License Considerations If your license is hosted on a server: Firewall Exceptions (both UDP and TCP) is open on the server’s firewall to allow the software to communicate with the license manager. Power Settings : The USB port on the server hosting the network key must be configured to stay active and not go to sleep 5. Operating System Compatibility Ensure your version of AccuMark is supported by your current Windows OS: AccuMark V10 and higher is required for Windows 10. AccuMark V8.2.2 and earlier not compatible with Windows 7, 8, or 10. If these steps do not resolve the issue, you may need a simple update file for your key; contact your local Lectra/Gerber support team with your key number ready.
