I have moved your post to a new thread, because you posted it in a very old thread.
Captivate has never been part of a creative suite (CS) as you mention. You probalby have a perpetual license, and need to contact Adobe Support with exact details about the version. This is mainly a user forum.
You talk about CP6. Which OS do you have now? CP6 is not compatible with Win10.
That is just up to you, I don't know what you want to do with Captivate. You can find an old PC to run CP6. You have to know that at that moment only SWF output was possible. Next year Flash Player will disappear from all browsers, which means that output will only be accessible by learners who are willing to keep old browser versions.
I am just a user, do NOT work for Adobe. What I tell you are some warnings. BTW Captivate still has a perpetual license to buy and a subscription license (which is more a hire).
