I just encountered this problem. The certificate is incorrect and cannot be installed. I struggled in various ways for a long time, a little crazy, but I still couldn't. Finally, I deleted the ie cache and the original installed components, and then downloaded all the components on the CCB website, such as enterprise version, 32-bit, 64-bit (mine is windows764-bit system), G&D, etc., and then downloaded and installed them all, and then started the computer. The payment was successful!

To sum up my experience:

1. Close all browsers and delete ie cache files with 360;

2. Uninstall the installed online banking security components;

3. Start the computer;

4. Go to CCB to download and install the security components suitable for your system (enter the U shield password, and you will be prompted to install the components. I'm sure there is something wrong with this security component, so don't install this);

5. Start the computer;

6. Turn on your mobile phone and see if you can pay. If the payment is successful, congratulations! If not, try to download and install all versions of security components like me, and then download them from.

I can feel your pain, because I have just experienced it, and I will answer your questions as soon as the payment is successful. I seldom answer questions, so I make an exception this time. I hope it helps you.
