When you install the Thunderbolt, the Thunderbolt will act as your default download tool, when you click on a download address, the Thunderbolt will be downloaded. However, when you find that you click on the download Address one day, Thunder does not have a pop-up window to download, then you can follow this tutorial to operate.
First step:
First turn on your "Thunder 5", and then left-click the top menu, "Tools" button, move the mouse to the "browser support" project, in the extended menu left click "Thunder as the IE default download tool."
Step Two:
The next pop-up "has the Thunderbolt set as IE's default download tool!" You need to turn off all IE browsers and reopen the settings to take effect! " This will successfully set the Thunderbolt as the default download tool, if there is a problem in the process, it is very likely that you have installed some "system optimization Software" (Magic Rabbit, XP master, Internet Assistant, etc.) to lock your registry, unable to write key values in the registry, please check that your registry is writable.
