What do you mean by "found and successfully installed the download"? Did you pay for the download? If so, you got the license code with it. Go to the first link in the post from DoninGA above for instructions to find the license code.
If you did not pay for the download, go to this link to purchase a download with a license code.
If you installed a download that you did not pay for, I don't know what you downloaded and installed. Where did you get it?
