Description The "Protected Mode" of the Internet Explorer (V7.8) 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".
Instructions Below is the procedure for disabling the "Protected Mode" of the Internet Explorer for trusted sites.
Start the Internet Explorer and open the settings of the Microsoft Internet Explorers by way of "Tools > Internet options".
Switch to the "Security" tab.
Mark the "Trusted sites" zone and disable the option "Enable Protected Mode (requires restarting the Internet Explorer)".

What is the meaning of the message "You must enable ActiveX Controls on your browser before you are able to install the WinCC Web Navigator Client software" and what can you do about it?
Description: Although you can load ActiveX Controls from other applications, you still get the message from the WinCC Web Navigator: "You must enable ActiveX Controls on your browser before you are able to install the WinCC Web Navigator Client software".

What causes the error message "Network request not supported" when starting the client Web Navigator site from the IIS?
Description In the Internet Service Manager (for Windows NT Workstation) or Internet Information Service (for Windows NT Server) on the WinCC server you want to start the website for the Web Navigator client and you get the error message: "Network request not supported".
Another website with the same port number as the Web Navigator website has already been started in the Internet Service Manager or Internet Information Service.

How can you avoid the "DEMO mode" of the WinCC Web Navigator client?
Description The mouse pointer on the Web Navigator client changes to a triangle with "NO INPUT" written in it although the Web Navigator client authorization is installed and the quantity framework has been kept to.
Procedure as from WinCC Web Navigator V7.0 You have set the authorization "1002 Web Access - monitoring only" for your user. This authorization permits the user to monitor, but not to operate.
Proceed as follows to assign the "Operate" authorization to this user. Open the WinCC User Administrator and remove the check mark for the authorization "1002 Web Access - monitoring only" of the user concerned. Now assign the required authorizations to this user.
Restart the WinCC Web Navigator client.
Procedure up to WinCC Web Navigator V6.2
You have set the authorization "1002 DataMonitor - Just monitor!" for your user. This authorization is reserved for the "SIMATIC WinCC/DataMonitor" option and requires a separate authorization.
Proceed as follows to assign the "Operate" authorization to this user. Open the WinCC User Administrator and remove the check mark for the authorization "1002 DataMonitor - Just monitor!" of the user concerned. Now assign the required authorizations to this user.

Why, after migration of a WinCC project from WinCC V5.1 to WinCC V6.0 SP1, is the text originally configured no longer displayed on the Web Navigator client, but only "TEXT" in buttons and in static texts?
Description Contrary to version V5.x, the Web Navigator users of WinCC V6.x are no longer managed in the Web Administrator, but along with other configurable WinCC users in the WinCC User Administrator. Regarding users already created in WinCC V5.1, the migration to V6.0 SP1 causes a loss of allocations between user and configured language, thus resulting in displaying the text as "TEXT".
Remedy: Delete the old users and recreate them with their corresponding language.
The Web Navigator CD provides the migration tool "WebNavV6Migration" to make use of the web users from Web Navigator V1.x in a WinCC V6.x Project. A description of the migration is available in the Web Navigator Help in the path "Configuration of the user administration > Migration of user data from old projects".

How can you prevent an empty page being displayed when you call the diagnostics information saved by the WinCC Web Navigator from the STATUS.HTML page?
If you have upgraded WinCC V6.0 SP1 and WinCC Web Navigator V6.0 to WinCC V6.0 SP2 and WinCC Web Navigator V6.0 SP1 respectively and have made a Microsoft update, the Web Navigator clients can no longer connect to the Web Navigator server.
The following error message is displayed:
"Microsoft VBScript runtime error '800a01b6'
Object does not support this property or method: 'rx.Multiline'
/Language.asp, line 218"
Sometimes in an Microsoft update routine not all the Dynamic Link Libraries (DLL) can be updated to the latest version. In this case, an older version of vbscript.dll is on the system, but the latest version is required.
Reinstall the Microsoft Internet Explorer to clear the error message. Then the Web Navigator client can once again connect to the Web Navigator server without any problems.
Why is there no automatic reconnect between a Web Navigator client and the Web Navigator server via a firewall or a proxy server?
Important In general, no warranty can be given for direct changes in the Registry, because this is entirely the responsibility of the user. In any event, you are advised to make a backup of the Registry before undertaking the actions described here. Furthermore, these settings are computer-specific. This means that when you copy the project to another computer, you must make the settings again.
