So your website requires an additional ActiveX control to work, no shame in that it’s not like HTML5 is perfect or that every browser has implemented all the features which everyone is dreaming of. You just need to do one small little change to your webpage so that Windows 8 users who are using Internet Explorer 10 in
Metro/Modern/Windows UI mode will be informed that they need to view the site in the desktop IE because ActiveX controls only work in desktop mode.
It’s a simple change, just add this line to the HEAD section of your webpage.
<meta http-equiv="X-UA-Compatible" content="requiresActiveX=true" />
While the name of the tag contains the word ActiveX, this holds true for ANY kind of browser plugin other than Flash which will only work in IE10 desktop mode under Windows 8.
