I tried many methods, set IE parameters, and F 12 entered the development mode to change the simulation, reinstalled the system, and found the problem was still the same. At first, I was also called the technical "auntie" of the Trademark Office. I heard that not many people get through, and I found that it is not as reliable as Du Niang. )

Web link Open the trademark online service system page, click "soft certificate replacement", and you will receive an email in about 3 minutes after submitting the information. The download link address should be the same as before. It is estimated that there is something wrong with the trademark network system, and the system information has been updated (personal guess).
2. Compatibility mode has been set on the soft certificate download page, and the association between third-party download software and IE has been cancelled. For example, IDM settings can temporarily uncheck IDM integration of IE browser. (This step may not be necessary)
Note: After clicking the download link, the installation will be completed automatically soon, and there is no installation package file.
