Additionally, this security update includes several nonsecurity-related fixes for Internet Explorer.

Known issues in this security update

To protect users against potentially unsafe ActiveX installers, the update installer is expected to fail under certain conditions on the following platforms:

  • Internet Explorer 9 running on Windows Vista and Windows Server 2008
  • Internet Explorer 8 running on any operating system
  • Internet Explorer 7 running on any operating system
On these platforms, you can expect ActiveX installations to fail if you are using a non-administrator account that has protected mode enabled.

To work around this problem, add the site to the Trusted sites list, or use the Run as administrator option to start Internet Explorer, and then install the ActiveX control.

Note If you install ActiveX on a per-user basis (this is the non-default scenario), the ActiveX installation may fail for the same reasons on all platforms. This includes Internet Explorer 10 and Internet Explorer 11. In this scenario, you should use this same workaround.
