Definite 5+ stars. The download is direct from Microsoft, and not from some obscure location. The license is immediately recognized by Microsoft. I had downloaded Office from another website, and MS rejected the license, as it could only be applied to the 3rd party download. Even then it was full of issues. Stick with a trusted source, e.g. Digital Zone Software. buy with confidence.
dosent work ...want my money back...Microsoft says i still need subsciption
Update. I did hear back from their tech. I had to activate via phone. Software works great now!
Worked like a charm upgrade to a win 7 pro version!
