Let me see if I can make a few educated guesses and save you some time:
You had Office 2004 running on your MacBook but recently upgraded to Lion (or Mountain Lion). When you attempt to run any component of Office 2004, you get a Dialog Box that PowerPC applications are no longer supported.
Your best and easiest solution (although maybe not the cheapest) is to upgrade to Office 2011 and everything should work fine again! 🙂
Two factual corrections:
1. Apple extensively publicized the fact that Lion would no longer include Rosetta. The problem is that the everyday normal PowerPC app Mac user had no idea what Rosetta was, that they were using it nor what its absence in Lion would mean for their everyday life!
2. Apple's license to use the underlying technology of Rosetta expired with the release of Lion (and now Mt. Lion). The third party company that licensed this technology to Apple back in 2005/2006, was acquired by IBM, who still champions the PowerPC platform.
It is doubtful that IBM would have re-licensed this technology to Apple at any reasonable price... Apple's "feelings" had nothing to do with it.
