Summary: Wash the discs!
Comment: Purchased July, 2008.
I'm not sure what rating to give this Office 2007 Professional upgrade, as it works well once you get it installed, but getting it installed was like having my teeth pulled!
I've read several reviews on this product, and found many of the reviewers frustrated with installs that would error off, portions of programs not working properly, and the like.
I too, had an install problem. First attempt wouldn't even open the install program. Changed drives, and it did open, but as soon as the install started, it would error off. I cleaned both drives, and tried again. This time it went partially through the install, and again it would error off, but the error message said "possible problem with install disc, notify Microsoft".
The disc looked fine to me, so I cleaned it with a lint free cloth as directed, and tried again. This time it got almost half way through the install before erroring off.
I finally tried washing it with soap and water, drying it with a lint free cloth, and trying again. Success! Installed perfectly the 1st time with no errors, and all programs that I use are functioning as they should (Word, Excel, PowerPoint, Access, Publisher)
CONCLUSION: Wash both discs in soap and water! The semi-sealed plastic case, is constructed of a hard plastic. There is a flap inside the pack that holds the discs and the book. This appears to be of a softer plastic. If stored in a hot, humid environment, or shipped on a very hot day, There MAY be a chemical reaction causing a film to form on the disc. (I'm not a chemical engineer, but I've seen this with some plastics in the past). Anyhow, that's all it took to get it to install and work perfectly. If you have the problem with your install, it's worth a try.
