How much memory need my computer to install dreamweaver

If I bought the program dreamweaver how much memory my computer needs to install and when I can download this program.

Here are the minimum system requirements for the latest Dreamweaver. Dreamweaver CS3 (2007).

* Microsoft® Windows® XP with Service Pack 2 or Windows Vista™ Home Premium, Business, Ultimate, or Enterprise (certified for 32-bit editions)
* 512MB of RAM
* 1GB of available hard-disk space (additional free space required during installation)
* 1,024x768 monitor resolution with 16-bit video card
* DVD-ROM drive
* Internet or phone connection required for product activation
* Broadband Internet connection required for Adobe Stock Photos* and other services

If you purchase a dreamweaver license online from Adobe's website (I think you can) then you'll be able to download it right away.

Or you can download the trial version of Dreamweaver CS3 and if you decide that you'd like to purchase it than you can buy a license, input it into the program and keep using Dreamweaver without having to re download or re-install it.
