Why am I seeing the error message 'Could not load TTWin kernel DLL - ttw4gui.dll'?

This issue is most common in Windows 7 and Windows Vista and occurs if the TTWeb site you are using has not been added to the Trusted Zone.

To correct this problem do the following:

  1. Load your TTWeb page with Internet Explorer, select the Tools icon, then Internet options.
  2. Select the Security Tab then the Trusted sites security zone.
  3. Select the Sites button. Your URL should already be in the "Add this website to the zone" box.
  4. Select the Add button.
  Please note: You will need to untick the "Require server verification (https:) for all sites in this zone", if your web site is using http instead of https.
