CS4: avviso del programma di installazione

[rob]

Comunque non puoi reinstallare una trial come tale. Devi acquistarla o installarla su un altro computer:

What if I get a trial version of a Creative Suite 4 edition, but have time to try only one or two components in the 30-day trial period? Can I still try the others later?
No. Each edition of Creative Suite 4 is a complete integrated product that is bound by the 30-day trial period. For example, Creative 4 Design Premium integrates these components: InDesign CS4, Photoshop CS4 Extended, Illustrator CS4, Flash CS4 Professional, Dreamweaver CS4, Fireworks CS4, and Acrobat 9 Pro with Adobe Bridge CS4, Device Central CS4, and Version Cue® CS4. Launching any one of these initiates the 30-day trial period. You must then evaluate these components within the 30-day window.

Can I extend the trial period longer than 30 days?
Unfortunately, you may not extend a trial version once it expires at the end of 30 days, nor can you install another copy of the same trial version onto the same computer to try again.

Can I convert my trial to an unrestricted version?
Yes. With Creative Suite 4, you can convert your trials with even more flexibility. If you have tried an individual component such as Photoshop Extended CS4, you can either convert that directly to the same product or convert it to one of the Creative Suite 4 editions that contains Photoshop CS4 Extended. Alternatively, if you tried an edition of Creative Suite 4 but decide to buy an individual component that is part of that edition, you can simply enter the serial number for the purchased product to convert your trial to the individual product you want.
