Please test whether downloading this installation package of Thunder is normal.

Download the website/xl7.9/intro.html.

If it is normal, it means that the resources you downloaded have become invalid.

If this is not normal, please exit antivirus software, Kingsoft software, 360, QQ housekeeper and other security software and download again.

None of them are effective. If you are a win7 win8 system, please exit Thunder and right-click Thunder shortcut-try to run in administrator mode.

If all the above are invalid, please delete this file through c: \ program files (x86) \ common files \ thundernetwork \ TP \ ver1

Then uninstall the Thunder reinstallation attempt.

I hope I can help you.
