Part 5: Best Practices for License File Management Avoid production halts with these professional habits. 1. Always Keep a Backup Store a copy of every license.dat file in a secure, offline location (e.g., a password-protected archive on a NAS). Label them clearly: Lectra_Modaris_V8R4_2024_Network_25users.dat 2. Document the Renewal Calendar License files often expire on January 1st or July 1st. Set calendar reminders 60 days before expiry. 3. Use Centralized License Monitoring For network licenses, use tools like Lectra License Administration Console (web-based) or lmstat to see who is using licenses and when. This helps justify purchasing additional seats. 4. Never Share License Files Publicly A license.dat file is legally binding and unique to you. Sharing it constitutes software piracy and exposes your HostID to malicious actors. 5. Virtual Machine Considerations If running Modaris on a VM (e.g., VMware Horizon or Citrix), you need a special “VM-aware” license or a USB dongle forwarded to the VM. Regular node-locked licenses tied to a virtual MAC address can break after VMotion migrations. Part 6: Frequently Asked Questions Q: Can I use the same license file on two different computers? A: For node-locked licenses, no. The HostID check will fail. For network licenses, yes, but only as many concurrent users as the license allows.
