Hello, I have a Powerbook G4, which I bought 2 years ago (1.67, etc., etc.), and recently bought a black MacBook for work and school. When I tried to install my MS Office 2004 (also bought 2 years ago, but with 3 licenses) on my new MacBook, it would run the installation script, but it would not recognize the cd once it came time to actually install the programs. Question is, do I need to buy an updated, "Universal" copy of office, or is there a way I can install this one. Question 2 (unrelated): Has anyone found a good safe cleaner for the Black Macbook besides water and microfiber? Thanks.
