Why can't I install Adobe CC trial with new account?

My issue is rather simple, I guess.

I recently installed the trial version for a set of Adobe CC products and later uninstalled them after the trial expired.

I soon realized that I had another Adobe account that had never been used for Adobe CC products.

So, I reinstalled Adobe CC manager and logged in with that account.

I then installed Dreamweaver CC, and came to find that the manager thinks I installed the trial with the new account (which I didn't).

Yes, I'm using the same computer, but if it's a different account, what gives? (Adobe account; not Windows)

I'm assuming it's due to something either in the registry or in some other file.

The reason I'm trying to "extend" my trial time is because 7-days is unrealistic and not even really enough time to "try out" their products.

Everyone's becoming real stingy on their trials and whatnot as of late. Not liking it.
