Good morning,
i had a problem with the hard drive and i replaced it. Zemax was installed on the previous hard drive. How do I reuse the license on the new one?

Hi @AmmA,

Sorry to hear about your licensing troubles, and hopefully you were able to remedy them. In the future, you certainly want to make sure to transfer the license before format, if possible. This Knowledgebase article has some good tips and tricks on how to do that for legacy licenses: Solving softkey activation or transfer errors (Zemax legacy) – Knowledgebase. For more specifics about your license, please contact academic@zemax.com to open a case to check on replacement or recovery.

Best,
Ethan
