If the automatic update fails, remove first the old version via Start / Control panel/ Programs and Features.
Next install the new version by clicking the Install button.

I did not buy a Microsoft security certification, so during the installation you will see messages like 'Setup.exe is not downloaded frequently and can be dangerous' and 'Your PC is protected'. Ignore these messages and choose actions like 'More information' and/or 'Nevertheless, do the installation'.
