- Deactivate all previous CS3 versions
If you’ve had any pre-release, public beta versions or if you’re simply reinstalling, make sure you open each program and choose “Deactivate…” from the Help menu.
Note to Adobe: Please add an automatic “Deactive” feature to the installer. You’ll get sooo many support calls from people that forgot to deactivate.
- Backup all your data
I know, I know; you keep all your files in a vault 400 feet below the bedrock. Great, just checking…
- Uninstall Apple Safari 3 beta
It’s known to cause conflicts with the CS3 installers.
- Uninstall all CS3 beta versions
You don’t want any of Adobe’s beta programs installed together with the officially released versions. Trust me on this. Please use the Adobe CS3Clean Script if you’ve had any of Adobe’s public beta CS3 versions installed on this machine.
If you’re on Mac OS X, here’s another catch: you can’t just throw the program folder into the Trash. I repeat: you can’t just throw the program folder into the Trash. Instead, in your Applications/Utilities folder, you’ll find an uninstaller called (for example) Premiere Pro Setup that you must use to completely uninstall any CS3 program.
UPDATE: If you are having problems running the CS3Clean script on Mac OS X (mine would just flash and close the CS3Clean.app without doing anything, make sure you are running it in super-admin mode by opening Terminal /Applications/Utilities/Terminal.app and then paste this command followed by the Return key:
…and then this command followed by the Return key:
sudo python ./CS3Clean.py
Then enter your administrator password to start the cleaning script.
Thanks to Mattias Werdenskog for the Unix skills required to pull this off!
- Defragment your harddrive
It’s 2007, and CS3 applications are huge. The more contiguous space you can provide on your harddrive, the better, so I suggest you defragment before installation, even if you’re on OS X.
- Be patient, and don’t surf while installing
Make sure you don’t need to use your computer for a while. Since the CS3 installers all use/modify the Flash plugin, you can’t have any web browsers open during the installation. And even if you can restart your browser while the installer is running in the background, it is not recommended at all. Just grab a coffee instead, OK?
Finally, if you still can’t get it to work, Adobe offers free installation support, check http://adobe.com/support/ for a local phone number.
I’ve also collected a bunch of steps to follow when troubleshooting After Effects.
Update: If the CS3 installer asks for CD 2 with the name of Adobe ExtendScript Toolkit2, the solution is to download this software, as described here.
