This problem occurs because Windows Internet Explorer 7 recognizes the MIME type of the digital license and determines that the link must be opened by using the Software Licensing Commerce Client (SLCC).

This problem may also occur if either of the following conditions is true:

•	An error occurs during the download process.
•	The Automatic Update Manager (AUM) does not correctly format the XML for the Digital License Package (DLP) before the download process is started.

To work around this problem, click the link that is included in the purchase confirmation e-mail to download the upgrade again.
