The C drive died and I am trying to activate CC on a new drive but cannot deactivate it on the old drive since it is dead. It is installed on a second computer too. Do I "kill" both activations from the CC panel and then reactivate them?
When you sign in on creative cloud desktop app on 3rd PC it prompts you to deactivate previous machines. You can simply select that option and proceed. In case it does not work please contact Adobe support.
