The "Protected Mode" of the Microsoft Internet Explorer is a feature that reduces the ability of malicious software being installed on your computer. The "Protected Mode" also affects the execution and display of ActiveX control elements used by the WinCC WebNavigator. The "Protected Mode" must therefore be disabled for the trusted sites, otherwise you get this error message displayed: "Low integrity level not supported - please disable Protected Mode".

No. Procedure
1 Start the Internet Explorer and open the settings of the Microsoft Internet Explorers by way of "Tools > Internet options".
