This problem can be solved from the following aspects:

1. locale and language locale have been modified. Make sure that the format and location of the regional language are set to China, and then restart the system to download the task again.

2. The influence of current optimization software, for example, WIN optimization main program, etc. This kind of software had better be shut down manually temporarily;

3, the hard disk itself: there is no need to reinstall Thunder 7, it is recommended to change the drive letter to download.

4. At the beginning-> Enter %temp% to close Thunderer during operation-> Delete all the cached files and restart the computer.

I hope I can help you.
