removing CS3 for CS4 (and CS5!)

[Todd Kopriva]

The short answer is that you should be safe uninstalling CS3 versions of the applications using the uninstaller (not doing it manually by deleting folders), as long as you do this _before_ you install the new version. You can mess things up if you uninstall the old version after you install the new version.

Since all After Effects plug-ins must be updated to new versions for After Effects CS5, this question is moot for moving to CS5. See this post by Michael Coleman.

Too late for that for me now. But for future reference, are you saying that uninstalling before upgrading will be safe as far as third-party filters are concerned?

I don’t know the details of all of the third-party installers.

as long as the licenses permit, the safest thing to do would be to uninstall all third party filters, then uninstall the old version of CS, then install the new version, and finally install the third party filters. You have to make sure though that the installer will let you use the same key (if there is one) on the same machine to reinstall – I don’t know about third party filters, but some software is one install only without the company’s approval, even on the same machine.
