Chromeleon License Activation [CERTIFIED • Tutorial]

Need to retire an old instrument PC? Here’s the safe migration path:

Choose the you want to activate.

Document Your License ID: Keep a secure record of your license key, purchase order, and activation date.
Deactivate Before Hardware Changes: If you replace a hard drive, motherboard, or reinstall Windows, deactivate the license first (License Manager > Deactivate). Failure to do so can orphan the license, requiring vendor intervention.
Periodic Revalidation: For regulated labs, treat license activation as part of your operational qualification (OQ). Document each activation and deactivation in your change control system.
Use a License Server for >3 Workstations: Managing individual node-locked licenses across a large lab becomes tedious. A floating license server simplifies deployment and tracking.

Audit Trail: Every license activation, deactivation, or rehost is recorded in the Windows Event Log under Applications and Services Logs > Thermo License Manager. You must include these logs in your audit trail review.
Separation of Duties: The person who activates the license (Admin) should not be a routine analyst (User). Configure local security policies to deny Users access to the License Administrator tool.
Validation: After activation, your OQ (Operational Qualification) must include a "License Loss Test." Disconnect the network cable to prove the software enters "grace period" mode without corrupting open sequences.
