After downloading this tool. Other languages such as Spanish, Italian are provided but English is not.
In addition there is no way to use the tool because when I request the activation code I am told that I've already registered.
How do we proceed to test the tool?

下载此工具后,虽然提供了西班牙语、意大利语等语言选项,但没有提供英语。
另外,当我申请激活码时,系统提示我已经注册,导致无法使用该工具。
我们该如何测试这个工具?
