Microsoft Filter Pack is not installed

[This topic is intended to address a specific issue called out by the Exchange Server Analyzer Tool. You should apply it only to systems that have had the Exchange Server Analyzer Tool run against them and are experiencing that specific issue. The Exchange Server Analyzer Tool, available as a free download, remotely collects configuration data from each server in the topology and automatically analyzes the data. The resulting report details important configuration issues, potential problems, and nondefault product settings. By following these recommendations, you can achieve better performance, scalability, reliability, and uptime. For more information about the tool or to download the latest versions, see "Microsoft Exchange Analyzers" at http://go.microsoft.com/fwlink/?linkid=34707.] 

Topic Last Modified: 2010-06-15

Microsoft® Exchange Best Practices Analyzer checks for the presence of the following registry entry to determine whether Microsoft Office 2010 Filter Packs are installed on the server that is running Microsoft Exchange Server:

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{64F1276A-7A68-4190-882C-5F14B7852019}\InprocServer32

The presence of this entry indicates that the Microsoft Office 2010 Filter Packs are installed on the target server that is running Exchange Server.

If the Analyzer tool determines that the Microsoft Office 2010 Filter Packs are not installed on the target server, the tool displays a warning. This warning indicates that the Microsoft Office 2010 Filter Packs should be installed.

To resolve this issue, download and install the Microsoft Office 2010 Filter Packs from the Microsoft Download Center.
