Error with Cisco Clean Access Agent

Hello,
I was trying to use the Clean Access Agent (CAA) after installation when I got this error message, see below.
I found a website on how to resolve this but when I tried following it, I still got this error message.
I knew the installation has completed when I tried using CAA.
I may have missed something. How would I know if the installation didn’t work?
Please help me resolve the problem.
Thanks in advance.
