The main reasons why the bank security control cannot be installed are as follows:

1. The customer is using a non-IE core browser.

2. Please check whether there is a firewall or anti-virus software on the computer that blocks the installation and use of the password control.

3. The IE browser is not set as the default.

4. The security control is not downloaded from the official website.

5. The customer's network is abnormal or the computer is blocked.

Solution:

1. Click Tools → Internet Options → Security on the browser menu bar, select the Internet zone, and select "Default Level".

2. Select 4 areas (Internet/Local Internet/Trusted Sites/Restricted Sites) in sequence, and click the "Default Level" button.

3. Click the "Advanced" tab and click "Restore Advanced/Default Settings".

4. After the setting is successful, download and log in the security control.

5. Be sure to download it from the official bank website through formal channels.

Extended information:

When installing a security control, you will be prompted where the control you want to install is used. You can choose the long-term form at home or on your own laptop. If you are in an Internet cafe or other place where privacy protection is not particularly good, do not choose the installation conditions at home, which may cause some unnecessary losses.

The installation of security controls can reduce unnecessary loss of accounts and operational errors, and plays a vital role in optimizing the network environment.
