Can I load Adobe CS3 and CS4 on the same machine?

Just a quick blog... As I transition into more use of the Adobe CS4 suite, and as I've seen some big changes here and there from CS3, I have had to ask myself:
Can I load CS3 and CS4 on the same machine?

From working with students who had this version or the other, I've seen that Adobe's made some significant changes to how the timeline and motion tweens work in Flash, and that some really sweet Photoshop commands from the Bridge are more work to "reload" than when they came automatically in CS3. I imagine there are other differences I'll run into, so I've been curious if I can't load both side-by-side, to have the option to use either one.

This type of thing is especially helpful for a trainer who may sometimes be called upon to teach either version while people decide if they really are ready to upgrade. But I have found that this can really just be a nice feeling for anyone who uses a suite or a product and is shocked to see big changes in a new version -- some of them unwelcome.

The short, general answer is yes. This type of thing is more common and possible than it used to be. I have Visual Studio 2005 and 2008 loaded on the same machine, for example. (And yes, I have licenses for both.) And my research suggested that the CS3 and CS4 suites may work the same, with the exception of that pesky Acrobat program, which evidently prefers you have only one version. That's fine: my Acrobat program loads seem to be so temperamental lately that I wouldn't mind a total refresh there.

I've now had both CS3 and CS4 suites loaded on my machine for a few weeks and enjoy the flexibility of being able to hop between whichever one I am more interested in or comfortable with at the time.
