Now available for download, the re-released November Community Technology Preview (CTP) for an Excel 2010 add-in, PowerPivot for Microsoft Excel 2010, is designed to resolve the expiration of the extension issue. The previous release expired, was time-bombed, last week but this new release fixes that and allows early adopters to continue testing the technology. Also, this new release is said to have the same and identical functionality as the earlier release with an expiration date that will last the rest of this year.
