Adobe CS6 Design and Web Premoum cannnot connect and Activate With Adobe in My Guest OS

I am in a bind, and only have 7 Days to figure this out, or my software will stop working, or so the screen message says.

I manamged to install the applications but now I cannnot activate them.

Some info;

I am on a Mac mini 2018, installed Adobe via Paralells desktop 18, in a guest OS macos sierra.

I had downloaded the dmg install file directly from my account, which I have and entred the serial number. It says I am not connceted to the internet. Yet I am, I was able to download the apps. I have gone through the steps of fixing or adjusting my interst conncetion but still no luck. I found the registrering offline info, and even foenloaded an online repair tool from Adobe, but thst did not work.

I really need this for a class that uses the software, and I cannot afford the expensive subscription plans for the cousre of 5 months for the class. I do not see why I cannot use what I already have.
