China Construction Bank's personal online banking signature control is not available.
According to your online banking detection control, your driver has been installed, and there is no problem. You may not have loaded the digital signature during the installation process (that is, a box pops up asking you to click Yes and No, but you clicked No). I suggest you delete the driver first, delete it directly from the control panel, and then reinstall it. Click Yes, and then check if it is ready. If not, you can ask additional questions.
