These updates are provided as Windows Installer Patch files (*.msp) to allow an easy installation and deployment. As these updates are cumulative, Sophos recommends using the latest version.

In this KBA you can download build version 30 of the filter driver engine. An overview of all File Encryption Engine Updates is available here. 

The following sections are covered:

  • Resolved Issues
  • Download and installation

How to verify if the patch is applied

After the installation, you can see the new File Encryption Engine in the Installed Updates section of Programs and Features. 

As this package just contains new filter drivers and no other products components, this update does not change the version or build number of the installed SafeGuard Client. In the SafeGuard Management Center version 8.20, the file filter engine version of this update (3.0.0.34) is also listed in the installed features list of the Client.
