The short answer is that the Personal Edition doesn't really support frameworks. The best option would be to use the full version of Pega - your company/project might have a test system or someone with experience installing it.
You can try installing it as normal, but it might not work. Getting the full version of Pega running will probably be easier in the long run if you need Agile Studio.
To get media, you should open a Media Request type Support Request (SR) through the My Support Portal and ask for both Pega Platform and Agile Studio. If you haven't opened an SR before, one of the other people in your office/ on your project should know how, and be able to give you the name of your Account Administrator if needed so you can open SRs that are linked to your company.
