The security control of Bank of China cannot be downloaded for the following reasons:

1. The "WEB" browser was not closed before running the installation package, resulting in incorrect installation. Please close the "WEB" browser first, and then download and install it again.

2. Software, such as Internet Assistant, which prohibits the installation and operation of controls is installed. Please modify its corresponding settings or delete the software in the control panel so that the plug-in can be installed and used normally.

Note: After installing the control, if the login page cannot be opened, please check the browser settings:

1. Select the "Advanced" option in the browser "Inter Options" and find that "Start third-party browser extension" is set to not enabled;

2. Select "Security" in the browser "Inter Options" and find that "Apply Pop-up Blocker" is set to be disabled;

3. Close all IE browser windows, and then reopen the browser to log in to online banking.

2. Why can't my Industrial Bank online banking work?

Industrial Bank's online banking cannot be used, probably because: 1, IE browser has not been upgraded, resulting in low encryption level and unable to enter the banking system; 2. Internet access environment or mode is limited, which may be the limitation of network service providers. If possible, change the way or environment of surfing the internet; 3. The network is blocked instantly, trying to refresh the page; If refreshing doesn't solve the problem, it may be because if the browser has set a cache, please click "Delete cookies" and "Delete files" in IE menu-Tools-Inter option to clear the temporary files.

4. If it still doesn't work, please add the website address of the bank to the trusted site, that is, browser-tools-interactive options-security-trusted site-site. If the above methods can't solve your problem, please call the bank's customer service phone for consultation and ask the bank's professional technicians to help you solve it.
