There are two reasons for this problem: first, when the content of the page has not been completely downloaded to the local area, clicking the trigger to run a program, but the program can not be found. At this time, as long as you wait patiently for IE's left foot to prompt "Finish", you can trigger the transaction. Second, because signing requires signing the control, if the control cannot be downloaded locally, this error will also be reported when the script in the page calls the control. At this point, you can manually register the signing control. First, download the control with the address of "/icbc/NetSign.dll", save this dll file in the system32 directory of the system, and click Start-run the execution command "regsvr32 NetSign.dll".

At the same time, it is best not to install software such as "372 1 internet assistant", which will hinder the download of security controls.
