We could reproduce this exception on Windows XP and Internet Explorer 6.0 with Ranorex V1.5.0.3184 and higher. IE 7.0 seems to be working fine, so does IE 6.0 on Windows 2000. We are currently working on this problem and will inform you as soon as we have a solution for it.

As a workaround you can use the Application.StartWindowsApplication and WebDocument.GetDocument methods to start a new IE instance and get the WebDocument from it:

Code: Select all

 Form ieForm = Application.StartWindowsApplication("iexplore.exe", "http://yourUrl.com");
WebDocument doc = WebDocument.GetDocument(ieForm);
