IE11 prevents ActiveX from running

Question

Our web browser plugin works fine in IE9 and IE10 but in IE11 the plugin is neither recognized as an add-on or allowed to run  It s as if IE11 no longer supports ActiveX   Surely there is a workaround but what do we need to change   NOTE  this questions is asked as the developer of the plugin and not the end-user who might need to correct IE settings

We started finding some machines with IE 11 not playing video  via flash  after we set the emulation mode of our app  web browser control  to 110001  Adding the meta tag to our htm files worked for us

Try this tag on the pages that use the ActiveX control     lt meta http-equiv  X-UA-Compatible  content  IE EmulateIE10  gt    Note  this has to be the very first element in the  lt head gt  section

Does IE11 displays any message relative to the blocked execution of your ActiveX    You should read this and this   Use the following JS function to detect support of ActiveX     function IsActiveXSupported         var isSupported   false       if window ActiveXObject            return true             if  ActiveXObject  in window            return true             try           var xmlDom   new ActiveXObject  Microsoft XMLDOM            isSupported   true        catch  e            if  e name      TypeError     e name      Error                 isSupported   true                       return isSupported

There is no solution to this problem  As of IE11 on Windows 8  Microsoft no longer allows ActiveX plugins to run in its browser space  There is absolutely nothing that a third party developer can do about it    A similar thing has recently happened with the Chrome browser which no longer supports NPAPI plugins  Instead Chrome only supports PPAPI plugins which are useless for system level tasks once performed by NPAPI plugins   So developers needing browser support for system interactive plugins can only recommend either the Firefox browser or the ASPS web browser

IE displays a active x warning and ask for permission if you allow it to run or not  To overcome this the only solution is to    Open Internet Explorer      Click the Tools menu  and then click Internet Options  On the Security tab  click the Custom level button   Scroll down the Security Settings list until you see ActiveX controls and plug-ins          For Automatic prompting for ActiveX controls  click Enable  Scroll down to Download signed ActiveX controls and click Enable or Prompt  Scroll down to Run ActiveX controls and plug-ins and click Enable or Prompt  Scroll down to Script ActiveX controls marked safe for scripting and click Enable or Prompt  Click OK  and then click OK again    There is no way to overcome this issue except changing manually Internet explorer settings  Try checking if plugin works fine while changed settings  If its still not working or not showing any warning is display try checking console for other errors which are not related to active x  Good luck

Here s how I got it working    Include your URL in IE Trusted Sites run gpedit msc  as Admin  and enable the following setting    gpedit- Local- Computer- Windows Comp- ActiveX Installer- ActiveX installation policy for sites in Trusted Zones  Enabled   Silently Silently Prompt   Run gpupdate Relaunch your Browser   NOTES  Windows 10 EDGE don t have trusted sites  so you have to use IE 11  Lots of folk moaning about that
