Ensure that your system meets the ActiveX Control system requirements:
-Windows 2000 SP4 or Windows XP/Windows ME/Windows 98
-Internet Explorer 6.0
-DirectX 9.0c
Ensure that your system has installed the latest Critical Updates from Windows Update.
Ensure that your Internet Explorer Security settings have been set to Low (temporarily) or at least enable ActiveX control settings.
If your system is using Symantec Internet Security Professional, ensure that it is disabled.
Temporarily disable any Anti-Virus software that may be installed.
Is it necessary to reboot the PC after upgrading the ActiveX control?
If you have been browsing a device that is using an old ActiveX control then switch to a device with a new ActiveX control in the same browser session,
after installing the new ActiveX control you will be prompted to reboot your
computer before the changes will take effect. In fact, you only need to
close all instances of Internet Explorer, then open a new instance and
browse to the device with the new ActiveX control. This time, after
installing the ActiveX control, you will not be prompted to reboot your
computer.
