Previously, when using IE8, after installing thunder, you only need to click the download link in IE8 to automatically open thunder, and then prompt whether to use thunder for download.
However, many users are unable to use thunder for download in IE9. When you click the download link in IE9, the built-in download manager tool is started by default. The following small series will give you the solution direction.
1. Open IE9, click the "tools" icon, and select "Manage Add-on"
2. In the add-on list on the right of the pop-up window, find the two add-ons "Thunder FLV video sniffing and download support" and "Thunder download support", and click either of these two options, click the "enable" button below;
In the displayed "whether to enable this add-on" dialog box, select "enable" to enable another add-on at the same time. (If this dialog box is not displayed, we only need to enable these two add-ons separately)
3. After the two add-ons are enabled, close the add-on manager and restart the IE 9 browser. Now we can call Thunder to download the plug-ins in IE9 by default.
Now, we can solve the problem that Xunlei is not the default in ie9. If you need it, refer to other.
