原因：没有开启ActiveX控件。
1、在打开的IE浏览器中选择 选项--Internet选项，
/iknow-pic.cdn.bcebos.com/d62a6059252dd42ad70c70b70c3b5bb5c9eab8a1"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/d62a6059252dd42ad70c70b70c3b5bb5c9eab8a1?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/d62a6059252dd42ad70c70b70c3b5bb5c9eab8a1"/>
2、在Internet选项窗口中选择"安全"在窗口的下面会有“自定义级别”点击进入。
/iknow-pic.cdn.bcebos.com/fc1f4134970a304e43e0d4e6dec8a786c8175cef"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/fc1f4134970a304e43e0d4e6dec8a786c8175cef?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/fc1f4134970a304e43e0d4e6dec8a786c8175cef"/>
3、然后在弹出来的“安全设置-Internet区域”中拖动窗口的滚动条，找到ActiveX控件和插件处继续向下移动找到“下载未签名的ActiveX控件”选项，将其选择“提示”，回车确定。

https://iknow-pic.cdn.bcebos.com/c2fdfc039245d688aac0c6b8abc27d1ed31b24ef"/>
4、然后回到安全窗口，选择“本地Internet”，打开“自定义”。
/iknow-pic.cdn.bcebos.com/279759ee3d6d55fb56ef013a62224f4a20a4dd85"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/279759ee3d6d55fb56ef013a62224f4a20a4dd85?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/279759ee3d6d55fb56ef013a62224f4a20a4dd85"/>
5、在本地Internet中将所有的ActiveX选项启用，
/iknow-pic.cdn.bcebos.com/37d3d539b6003af33187ab7c3a2ac65c1038b6e8"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/37d3d539b6003af33187ab7c3a2ac65c1038b6e8?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/37d3d539b6003af33187ab7c3a2ac65c1038b6e8"/>
6、再将下面的“下载”内容中的“文件下载”、“文件下载提示”启用。
/iknow-pic.cdn.bcebos.com/77c6a7efce1b9d16c0efed7dfcdeb48f8c546485"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/77c6a7efce1b9d16c0efed7dfcdeb48f8c546485?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/77c6a7efce1b9d16c0efed7dfcdeb48f8c546485"/>
7、配置可信任站点级别，首先将所有区域重置为默认级别，
/iknow-pic.cdn.bcebos.com/5fdf8db1cb13495444539978594e9258d1094a58"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/5fdf8db1cb13495444539978594e9258d1094a58?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/5fdf8db1cb13495444539978594e9258d1094a58"/>
8、添加可信网站地址，点击站点。
/iknow-pic.cdn.bcebos.com/21a4462309f790527231362203f3d7ca7bcbd584"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/21a4462309f790527231362203f3d7ca7bcbd584?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/21a4462309f790527231362203f3d7ca7bcbd584"/>
9、可信站点地址输入框--输入需要的地址，如果是https的地址直接点添加，如果不是请取消https选项。
/iknow-pic.cdn.bcebos.com/0eb30f2442a7d9335ee1956fa24bd11373f00164"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/0eb30f2442a7d9335ee1956fa24bd11373f00164?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/0eb30f2442a7d9335ee1956fa24bd11373f00164"/>
10、然后就可以正常浏览了。
