Error on Configure Active Directory Certificate Services on the Destination Server

Hi guys, I'm quite new to active directory and I hope that you can help me out. My primary goal is to set up Certificate Services. I have already installed the role "Active Directory Certificate Services", with Certification Authority Authority Installed. Next step from the guide that I use is to "Configure Active Directory Certificate Services on the Destination Server".

I am using Domain\Administrator account on setting it up, ticked Certification Authority, then set up type, Enterprise CA. As soon as I hit on "Next", I get a pop up that says below:

"CcertSrvSetup: SetDatabaseInformation: The system cannot find the pat specified: 0x80070003(Win32: 3 error_path_not_found)

I have searched everywhere but cannot seem to find an exact issue as I am having. Any help would be appreciated. Thank you.
