Navigate to the local licensing directory, typically located at: C:\ProgramData\DassaultSystemes\Licenses
Sometimes, the local license cache becomes corrupted and holds an "expired" token even after renewal.
The expiration date of Catia licenses marks a significant milestone for users, requiring them to reassess their software strategies and plan for the future. While there are challenges associated with expiring licenses, users can take proactive steps to ensure business continuity, minimize risks, and explore new opportunities for growth and innovation.
