Error Message: Error loading component. Can’t load secbuff library. Please reinstall.

This error usually occurs if the MSI package is not being run as a Windows Administrator and Windows UAC is turned on.

This error can still occur however even if you are logged on as a Windows administrator and UAC is turned off because Windows Installer by default doesn’t elevate to higher privileges until it is about to actually start doing work in the install sequence.

To force Windows to run the MSI package with Admin Rights, download the registry fix that enables you to right-click on MSI files and select ‘Run As Administrator’.  This can be downloaded from http://www.symantec.com/connect/sites/default/files/MsiRunAsAdmin.zip.

Once this has been installed you will be able to right-click on the MSI setp file and select the option ‘Run As Administrator‘, forcing Windows Admin Rights on the installation.
