• (Recommended option) Save this file with the extension .hta (do not save an .mht ‘web archive’, just this single HTML page).

  

  Open this file.

  

• (Less safe option, but you won’t need to download again when there’s an update) Open this page in IE. Enter Internet Options, tab [Security]. Select the ‘Trusted sites’ zone and drag the security level slider to ‘Low’ for this zone.

  

  Then click the [Sites...] button and add this page to your trusted sites list.

  

  Additionally, you may click [Custom level...] in the previous window and change the ‘Initialize and script ActiveX controls not marked as safe for scripting’ setting to ‘Enabled’.

  

  Then refresh this page.
