I recently purchased a new Alum 24" iMac. Over the past two weeks, I've been trying to install CS3 Design Premium. The installation appears to act as normal (although it's extremely slow), but at the end of the process it reports with a red X, "Photoshop CS could not be installed." • Re-run the setup program. Same error persists. • Downloaded Adobe's CS3 Clean Script (http://www.adobe.com/support/contact/cs3clean.html), and re-run setup again. Same issue (Performed both Level 2, and the secret Level 3 options). • I erased and reinstalled Mac OS X (10.4.10). The installation again installs every application except Photoshop CS. • Tried to just install Photoshop CS 3. Works fine if installing after Clean Script. However, all other components will fail if attempting to install them after installing Photoshop. Any ideas? Adobe Technical Support was absolutely no help. They suggested I spend $20 to have them send out replacement installation discs. By the way, the entire Adobe CS 3 Setup (from the same discs) runs perfectly fine on my MacBook and 20" iMac (Core Duo).
