Instalation Issues of CS6 after HD crash and repacement of the HD.

[Marjan0D4C]

Dear community
I am a teacher and my iMAC has recently crashed.
I had to replace the HD and now I would like to install CS6 Design Standard again (Education edition)?
I can not deactivate or Activate my account because there is no link to my computer.
My product is registered but do I have to add the serial number again?
What can I do to make this work again?
Regards Marjan from Belgium

You may need to enter the serial number. 

If you need to reset activations:

Go to chat and only ask to have your activations reset:

Type "Agent" in the chat box to bypass the chatbot and be connected to a person.

You may also be able to contact Adobe by phone:

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 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 or Big Sur. Only the latest Creative Cloud products are compatible.

NOTE 3: Legacy Creative Suite is discontinued & unsupported. Use at your own risk.
