Do you mean you have a Creative Cloud subscription?
Or that you purchased a download?
If you have a subscription, you just sign in with your AdobeID.
If you purchased a download, then you were given a serial number when you purchased it, and need to use that serial number. If you can't find the serial number, it will be listed in your account information on adobe.com.
