DO read the "readme" files contained on the Photoshop installation CD and the readme file that is placed in the Photoshop application folder after you install Photoshop. They both contain useful information about installation, compatibility, and last minute updates that didn't make it into the product documentation.
DO have your previous version installation disc or serial number handy before installing, if you do not already have a previous version installed on the same computer. If you are upgrading from a previous version, you do not need to have the earlier version installed on your computer, but if you don't, you will need the CD or serial number from your previous version. If you cannot locate the CD from your previous version, you will have to call Adobe to have them walk you through the unlock procedure (have your serial number ready). For upgrades to version 7.0 and later, prior serial numbers will no longer work. You will need to use the new 24-digit serial number provided in your upgrade package. For upgrades from very old versions (4.0 and earlier), you will need to contact Adobe technical support at 800-685-3658.
DO log on as administrator if you are installing Photoshop on Windows 2000 or Windows XP.
DO keep your quick reference card handy while you are still new to an upgraded version. Whenever you can't find a tool or command that you've been used to seeing in your earlier version, you can quickly find the new information here. (Note: Photoshop CS and up don't have a quick reference card, but you can create custom keyboard shortcuts and print a shortcut key reference chart.)
DO explore the contents of the Photoshop installation CD. You'll find some great stuff in the GOODIES folder stock art, presets, color swatches, and more. The CD also includes trial versions of several third-party plug-ins, Adobe product tryouts and PDF documents detailing the new features in Photoshop.
DON'T install Photoshop to the same folder as a previous version. Photoshop is intended to be installed to a new folder with each new version. If you're installing to a location other than the default, you'll need to specify a complete installation path including a folder (i.e. D:\Photoshop 7.0 not D:\). If you don't, you'll have a real mess to clean up.
DON'T attempt to move all the plugins from your old version to the new plug-ins directory. Most plug-ins will need to be reinstalled. For more about transferring your plugins to the new version, see the additional information in part four.
DON'T remove your old version until you feel confident that you're up to speed with the new version. When you're working on a deadline, you won't be able to work as quickly in an unfamiliar environment. You can save yourself a lot of frustration by doing work in the familiar version when you're in a time crunch. When you feel like you no longer need your old version, it is perfectly safe to uninstall it.
DON'T forget to copy over any custom files before removing your old version. This includes actions, custom brushes, color palettes, gradients, textures, styles, tool presets, etc. that you have created, purchased, or downloaded. Unlike plug-ins, these can be moved to your new Photoshop folder without any problem, but they'll need to be loaded from the appropriate palette in Photoshop before you can use them. These are usually stored in sub-folders of the program installation folder (for example: "C:\Program Files\Adobe\Adobe Photoshop CS\Presets\Brushes" for brushes). You will want to copy all your custom brushes from the old version program folder to the new one. Same for actions, pattern sets, layer styles, gradients, and so on. You may event want to copy the entire "Presets" folder to another location (such as CD) for safe keeping.
