Troubleshooting common license issues (actionable fixes)

• Software reports “license not found” or “trial mode”:
  • Confirm dongle plugged in; try different USB port; reinstall dongle drivers; check Device Manager for driver errors.
  • If node-locked, confirm activation file matches the workstation hardware ID; regenerate or request re-issue from Siemens if hardware changed.
• Activation fails due to network or firewall:
  • Temporarily allow outbound connections for Siemens activation endpoints or follow offline activation instructions.
• License shows fewer seats than expected:
  • Check if license is concurrent and in use elsewhere; check license server logs; ensure license server time is correct.
• After hardware replacement, license invalid:
  • Contact Siemens/reseller to request transfer or reissue per their transfer policy.
• Corrupt license files:
  • Restore from backup or contact Siemens support for reissue (have proof of purchase ready).

• Obtain license only from Siemens or authorized reseller.
• Choose appropriate license type (node-locked, dongle, or floating).
• Keep secure backups of license information and receipts.
• Follow Siemens activation instructions; contact support with proof of purchase if problems occur.
