You haven't 'not found them' on the disk, they are not there. Internet is the way Adobe has chosen to deliver them.

The bottom line is: for Premiere Elements 11 and 12, Content download is now only from Adobe as a download whether you have purchased installation files from an online download from Adobe or have purchased an installation disc. No workarounds.
The situation is detailed in my blog post on the subject, and it includes a suggestion for making your own Content disc but only after
the time consuming task of downloading the Content from within the project for each of the categories of Content.
Have you looked at the approach of right clicking the blue ban at the top right corner of the Content of interest, selecting Download All, and then clicking on the option to download in background?
Please review and consider. And, please do not hesitate to ask questions or ask for clarification.
Thank you. Irritating, but that's insanity!!!
Thank you very much!
