Warning Info

The CSClientManagerPrj control does not have a valid digital signature to verify its publisher.

Process——

According to the warning, the CSClientManagerPrj control does not have a valid digital signature to verify its publisher. That is to say, the IE browser does not trust the digital signature of this control. After learning this Info, I checked the advanced settings of the IE browser and found that it did not allow untrusted signatures to install controls. After checking, Restart IE to test and you can access it normally.

Root cause

The root cause is the signature of the CSClientManagerPrj control. IE thinks there is a problem, so it cannot install the control.

solution

The solution is to modify the advanced options of the IE browser so that the IE browser does not intercept untrusted digital signatures and allows them to be installed normally.
