need help installing older version - doesn't like my s/n

[Robyn5CF8]

I had to get a new computer & all my software had to be reloaded.

My Adobe Pro is an older version on CD. I don't have a CD drive now.

I tried using a backup copy of my Adobe & reinstalling but the install will not accept my S/N.

How do I reinstall or reach a tech to chat?

Warning, scammers may contact you privately pretending to be Adobe staff. Adobe will never send you a private message asking you to email an account that isn't @adobe.com, or use Skype. Adobe never ask you for their password. These scammers want your Adobe info, credit cards, your money and control of your computer, please take care.

You need to buy an external DVD drive

Adobe has removed ALL public download links for installs and updates
-links are ONLY available to someone who purchased a download from Adobe
-CS6 (and earlier) are no longer sold or supported by Adobe, and no authorized
-vendor has copies to sell... not by disc, and not by download of an installer

The Adobe employee who advises volunteer helpers (I am one) said this on 12-18-2019
"Adobe employees will no longer be engaging with Creative Suite customers to provide support via chat, phone, or social media"

That means that you will not be given a download link by contacting customer support
