Installing CS4 from CS3 question

Hi everyone, I'm new here. I own the Adobe Creative Suite CS3 Web Premium and I just purchased the Adobe Production Premium CS4. I just rebuilt the machine with Vista 64 and am about to reinstall all the software. I'm trying to figure out if I can skip Photoshop CS3, Illustrator CS3 and Version Cue CS3 when I install the CS3 suite and just use the ones that came with CS4 or is this going to cause any issues? (i.e. should I also install the CS3 versions?). I was told to make sure I install the Flash CS3 before the Flash CS4, but what about Photoshop and Illustrator?

Thanks a bunch,

Roberto

Roberto: Don't need to re-install CS3, when installing CS4, if it asks, just pop in the CS3 DVD for verification.

I ended up reinstalling both. CS3 Suite is the Web premium, whereas CS4 is the Production Suite. They have a couple of apps in common (Photoshop and Illustrator) and that's about it. I decided to install both completely and just not use the CS3 apps that were ported to CS4.

Thanks,

Roberto
