CS1, CS2, CS3 and CS4 activation servers are dead & gone. It's impossible to activate the software now.
CS5 and CS6 are on life support. But they can still be activated providing you have the following: 1. your original media (disks or downloads) you received at purchase and a way to read them, 2. a legitimate serial number for that version, language and platform (Win/Mac) and if it was an upgrade, a qualifying serial number from an older product, 3. an older operating system that can support legacy 32-bit apps.
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 newer systems.
NOTE 3: Legacy Creative Suite is discontinued & unsupported. Use at your own risk.
