Troubleshooting Mastercam X5: How to Fix the "No SIM Found" Error
A functional USB HASP key should emit a solid red light. If the light is off or blinking, the port lacks power or the dongle is defective. 2. Run Mastercam as an Administrator mastercam x5 no sim found
For machinists, CNC programmers, and manufacturing engineers, this error is a productivity killer. Mastercam X5, despite being a legacy version (released around 2010), remains a workhorse in many small to medium-sized shops that don’t want to pay for expensive annual upgrades. But its age means it is notoriously finicky with modern operating systems, USB drivers, and security software.

Mastercam X5 relies on a Security Information Module (SIM) to verify licensing. This module usually takes the form of a physical HASP USB key or a NetHASP network license. When you see the "No SIM Found" message, the software's execution path is blocked because the license handshake failed. This issue typically stems from three main areas:
Ensure the setting matches your hardware—select HASP if you have a physical USB key plugged into your local machine, or NetHASP if your license is managed over a network. This error means that Mastercam X5 cannot detect
Windows Updates can sometimes break the Sentinel/SafeNet drivers that Mastercam uses to communicate with the SIM.
The "No SIM Found" error in Mastercam X5 is a frequent disruption for CNC programmers and machinists. This error indicates that the software cannot detect the physical USB security dongle (Hasp) or the software license required to validate your access.
Sometimes a bad driver update (specifically SafeNet 6.55) causes this error. Open . Expand Universal Serial Bus controllers . Look for "SafeNet Inc. Hasp Key."
Extract the files to an easily accessible folder (e.g., C:\Hasp ). Open as an Administrator. Type cd C:\Hasp (or your specific path) and press Enter. Check the box for and select Windows 7
What is your CNC programming computer running?
Security software may mistakenly block the license communication service.
For Mastercam X5, the most permanent solution is a clean driver reinstallation. Do not use the latest drivers from SafeNet; use the legacy drivers from the Mastercam X5 installation directory.
Old software requires old permissions.
