How do I register for CS4 when I'm subbed to CC?

[HAEGOE]

I'm currently subscribing for Adobe animate CC, and I'm trying to use Flash CS4 with it because I liked the old brush function.

I couldn't find how to log in to CS4 and register with my CC account, and if that's even possible.

So... like I said in the title, how do I register for that?

You can't link it to CC. If you have the disks and serial number you may be able to install the old app, though it's questionable whether it will work.
