Returns or sets whether to use ActiveX for IE 10 and 11.
By default, the HTML5 edition is used on IE 10 and 11, in some cases, you might want to keep using ActiveX on IE 6 through 11. To do this, you can set IfUseActiveXForIE10Plus to true. But it's important to note that this needs to be done in the file dynamsoft.webtwain.initiate.js.
Dynamsoft.WebTwainEnv.IfUseActiveXForIE10Plus = true; /*Change false to true, if you don't find this line just copy this line to your dynamsoft.webtwain.initiate.js*/
