Opening a docx document in IE

Dear All,

My goal is to open a .docx document in a web browser.

I have downloaded the OpenXML viewer for internet explorer, thus if I drag a .docx document and drop it in Internet Explorer browser, the file content are displayed on the page.

However, if I try to load the file into a webBrowser control (C# or vb.net) using the webbrowser.navigate("filepath"), the file opens on as separate word office document.

I have been looking for solutions without success,
some say we should add a registry entry for the application within  to "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION"

Any Help is much appreciated.
