This FAQ describes important changes related to security enhancements in the latest updates of the macOS 15 and Windows 10-2H22 operating systems. It is required that affected users of easyDCP Plus and IMF Studio update to version 4.2.4 (or higher).

A key point here is that existing signer and server certificates must be replaced with the update to version 4.2.4 (or higher). As a result, previously received KDMs (Key Delivery Messages) or DKDMs (Distribution Key Delivery Messages) become invalid. 
Users should prepare accordingly and ensure that previous KDMs/DKDMs may need to be renewed after this update.

This affects both online and offline-activated easyDCP Plus and IMF Studio 4.2.4 (or higher) applications. 

Procedure for online activation:

• The new 4.2.4 (or higher) application starts as usual with online registration.
• After entering the access data, this message appears: 

• After confirming the “OK” button, the new certificates are created and loaded automatically. 

Procedure for licenses used with offline activation:

• The new easyDCP applications always start with the online activation mode for the first time during the update (even if previous versions ≤ 4.2.3 were already installed in offline mode).
• Switch to demo mode and carry out a offline activation.
• By reactivating, you will receive a License & Certificate Data Set with new certificates. 

This update is also recommended for users who are not yet using the updated operating systems. As far as the operating system allows, you can use earlier easyDCP Plus and/or IMF Studio versions in parallel to the new version and continue to use the previous certificates.
