Unable to use product trial key for Powerpoint 60 day free trial

I see from previous emails about "Product Key not working on Office Trial" that it will never work b/c it is for Windows, not office. I registerd for 60 day free trial at Microsoft online...all went ok and was sent welcome email with 25 digit product trial key. It does not work...whe did they send it to me if it was for Windows, not office....How do I get to use my free trial?
OR do they just want me to go out and buy the product?
Then do not call it A Free Trial...
