We're seeing the same issue here. IE v11.0.9600.18638 (running under W7 ENT 64-bit) will launch, but it never displays any content in the window or in the URL field. Entering a URL fails to produce any content or any indication that IE is attempting to load a site. Clicking on the IE "Config Wheel" shows most of the options are greyed out", though Internet Options can be accessed via Control Panels-->Internet Options instead. Closing and quitting IE may or may not allow normal behavior. Stopping and disabling the MBAE service and restarting appears to correct the issue. We're running MBAE 1.09.2.1384 via MWB Console v184.108.40.20608 with MBAE client set up auto-update.
Thank you for looking into this issue!
