Summary Checklist
If you are still stuck, check these final details:
- System ID Mismatch: Did you change your hardware (RAM, Hard Drive) recently? The license is tied to your hardware "fingerprint." If you changed hardware, you must contact CSI to regenerate the license key based on your new Machine ID.
- Version Mismatch: Are you using a license for ETABS 2015 on ETABS 2016? The license keys are version-specific. You cannot run 2016 with a 2015 license key.
Resolution:
The most reliable fix is usually Phase 1 (checking the lservrc file). However, if you have recently updated Windows or changed hardware, you likely require a new license key generation from CSI Support. CSI Technical Support : Reach out to Computers
