Winform WebBrowser Not Displaying CSS

I am trying to navigate to Flying Toasters in the Winform WebBrowser Control, but the animation seems to hang at the first frame. I am guessing this is a compatibility issue with the web browser because when I navigate to other websites it says "IE7 and IE8 are no longer supported". Why is this happening and is there any way I can fix this?

Internet Explorer 7 rendering will be used if you do not override the Feature Browser Emultate setting in the registry.

For your user (Current User) only use this key:

  • HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION

For all users on the computer/server use this key:

  • On 64 bit app on 64 bit- or 32 bit app on 32 bit machine:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION

  • On 32 bit app on 64 bit machine:

    HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION

For example if your executable is named flying_toaster.exe. You will have to add an DWORD entry with the name flying_toaster.exe and with a value 11001 (to use Internet Exlporer 11-rendering).

enter image description here

A complete list of values is listed below (quoted from MSDN):

11001 (0x2AF9) Internet Explorer 11. Webpages are displayed in IE11 edge mode, regardless of the !DOCTYPE directive.

11000 (0x2AF8) IE11. Webpages containing standards-based !DOCTYPE directives are displayed in IE11 edge mode. Default value for IE11.
