Matériel HS comment récupérer mon ancien produit

CS5 and CS6 are discontinued and on life support. But they can still be activated providing you have the following:
1. your original installers (disks or downloads) that you received at purchase and a DVD/CD reader to read them.
2. A legitimate serial number for that language, version and platform (Win/Mac).  And, if it was an upgrade, a qualifying serial number from an older product.  You may find your serial numbers online at  https://account.adobe.com/products
3. You also need an older operating system that can support legacy 32-bit apps.

NOTE 1 : Creative Suite installers won't work on macOS Sierra, High Sierra or Mojave without terminal workarounds. See the help article below.

NOTE 2: Legacy Creative Suite will never run on Catalina, Big Sur or Monterey. Nor will it be tested on Win 11. Only the latest Creative Cloud products are compatible with new systems.

Beware of fake Adobe reps who may contact you privately offering to sell you software or take control of your computer. It's a scam, run away! Real Adobe employees will never reach out via Outlook, Yahoo, Gmail or Skype.
