BUT WHY?!
...you don't need to do that anymore - you just need to create an Adobe Creative Cloud account (free) and then add your credit card details. A desktop app will download to your computer, where it will show you all the various apps available from Adobe. You can click on any one at a time, or you can pay for the entire suite (package) for a once-off fee. The 'buy' button will take you to payment page where you will be required to enter your credit card details... and voila. You have any or all the Adobe apps on your computer. Your cloud app on your computer will give you full info and access to the various apps, so you can manage them by just the click of a button.
