We are a country, the problem with your network operator can't download, and you don't seem to use the software, the download must be fully accessible through the proxy network.
Again, I suggest that you do not repeat the post. The first post should be in pure English. It is not suitable for mixed use of Chinese and English. The forum staff will cause confusion and will not reply to your question.
When you do not know how to use the software, after contacting me, I will provide remote assistance and tell you how to download and use the software normally. I am also researching the usage of the software myself.
