Just installed upgrade to CS5, now have both showing in Finder

Question

I installed the upgrade and assumed it would remove the irrelevant parts of CS4 and upgrade the rest to CS5 - now my Applications Folder has a CS4 and CS5 version of everything. Should I just drag the CS4s to the trash? Was I supposed to have uninstalled before upgrading?
Thanks,
Cailin

????!!!??? A little late aren't you? This was completed in June.
However, for your benefit, this issue hinged on why adobe felt that it was necessary for purchasers of CS5 to keep both the full CS5 and CS4 programs installed on the PC's at the same time after the upgrade taking up disk space. Other software developers have made their new version backwards compatible rather than assuming that every user had unlimited space on their hard disks and needed to retain both versions. So CS5 is not a true upgrade but a fully functional stand alone version and the only programmed upgrade factor was that it needed to prove the existence of the earlier version to prove that the upgrade discount was justified. Not a technical issue....economic.
Also, the second issue was in respect of the method advised to uninstall. I have never before heard a recommendation to uninstall a complex program by drag and drop into a recycle bin. This would leave vast amounts of orphan files around the system as well as very many registry entries which have the potential to cause future system conflicts.
The question about uninstalling CS4 after having installed CS5 was an important one. I had asked the question becasue it was very likely that both versions would be using a number of common system files and the concern was that if CS4 was uninstalled the potential existed that the process would uninstall certain system files essential to the proper working of CS5.
As said, I resolved the issue in June which is why there have been no subsequent posts.
