No serial number is needed to download or run the trials. What’s more, a single CS5 purchase may entitle you to install and activate the software on two systems with certain restrictions. If you’re upgrading to CS5, you can install a trial and then buy an upgrade to convert your trial into a purchased version. Also, the trials for the suites do not bundle Acrobat 9 Pro – so it must be downloaded separately. * The same thing goes for CS5 Design Premium and Design Standard – you get the bigger one and choose later. You decide which you wish to activate at the time of purchase. Note there is a single trial download for Photoshop – it’s Photoshop CS5 Extended, which includes the Standard version. The Windows or Mac downloads can be installed on multiple computers if desired – and if and when you are ready to buy, you can easily convert your trial to permanent unrestricted use without reinstalling the software in most cases: Click to immediately download whichever you like, from Photoshop CS5 to Master Collection!Īll CS5 trials are fully functional for thirty days and can run side-by-side on your system with older versions, without interference.
