Internet Explorer blocks out-of-date ActiveX controls. This does not affect Sinch Contact Pro end-user applications but Infrastructure Administrator and System Configurator users may encounter this in environments where the Java SE 8 version below update 11 is used.

If this may happen, note that:

  • IE does not block the usage but displays a warning. You can choose to use the blocked Java by selecting Run this time.

  • Blocking is not applied to Local Intranet Zone or Trusted Sites Zone. Make sure that the Remote Administration Tools site is on an appropriate zone.

  • Install the prerequisite software security updates when available.
