How to install Adobe Photoshop CS3 on Mac OS X

Yesterday, I upgraded to Adobe Photoshop CS3 for Mac OS X and had to jump through some hoops to get it to successfully install. If you have been using the old Photoshop CS3 beta, you have to uninstall the application by using the script in Applications/Utilities/Adobe Installers. You cannot just drag the app to the trash. I also had to run the Adobe CS3Clean script before the new CS3 would install. Some folks have been saying that they have had to uninstall Photoshop CS2 and all other CS2 applications before CS3 would install, but I was able to install without doing that. However, Adobe Bridge CS2 no longer works on my system. Luckily, I never use Bridge, and don't really care if the CS2 version doesn't work.
