exception EVsEmbeddedBrowserError - ORF Forums

@tom.ganus2: Hello Tom,

ORF relies on embedded system web browsers to render rich UI in the ORF administrative components. Internet Explorer also relies on the system web browser internally and some IE settings may affect other programs (like ORF) using embedded browsers. In this case, I suspect that your Group Policy locks down IE quite hard and disables JavaScript one way or another.

To prevent conflicts between IE settings and embedded browser settings, ORF implements its own security manager and maps all internal resources to the LOCAL_MACHINE security zone. The LOCAL_MACHINE zone is quite special and its settings cannot be edited in Internet Explorer. This provides some guarantee that user settings will not affect ORF, but Group Policy and direct registry editing can still manipulate settings for this zone.

I am afraid I cannot tell which settings to look for exactly without seeing the settings myself, but if you can recall any recent IE registry changes or GPO changes, that should be a good start. In the past, we had a similar issue when "Enable MIME Sniffing" was turned off for the Local Machine Zone. A telltale sign of this is if you see raw HTML source code on the ORF user interface.

The KB article below explains some of the IE security settings in the Group Policy and provides hints on where you find them: https://support.microsoft.com/en-us/kb/182569

Let me know if this has helped.

@tom.ganus2: Hello Tom,

Did ORF ever work on this computer? If it did, can you think of any change to the server (e.g. Windows Updates) between the last time it worked and the issue?

Also, when you get this error and close the dialog, do you get HTML source displayed in the ORF tool windows?

In any case, the problem definitely has to do with the LOCAL_MACHINE security zone settings. Can you please send us a screenshot of all keys or an export of your registry at HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\0 to ? Be sure to open the registry editor with user experiencing this issue.

@tom.ganus2: No, ORF does not require Java. ORF displays embedded HTML content, however, and interacts with that HTML using JavaScript, much like a website. JavaScript and Java have misleadingly similar names, but they have nothing to do with each other really and you do not need Java to run JavaScript.
