Contact Expert Agent Client with legacy scripting throws script error when click on the next or previous button in the legacy script and the agent can not navigate in the script.
The issue occurs on Window 10 after applying KB4493509.
- Since Windows 10 build 16237: “VBScript is deprecated in Internet Explorer 11, and is not executed for web pages displayed in IE11 mode. However, for backward compatibility, VBScript execution is currently still permitted for websites rendered in legacy document modes. This was introduced as a temporary solution. Document modes are deprecated in Windows 10 and not supported at all in Microsoft Edge”.
- Since windows update KB4493509 (build 17763): Internet Explorer will not run VBScript from websites that use Internet Explorer’s legacy document modes (Internet Explorer 10 and earlier versions), and that are in the Internet Zone or Restricted Sites Zone."
Explicitly enable VBScript execution for websites in Internet Zone and Restricted Sites Zone using Windows registry or Group Policy settings.
