You didn’t answer the question. For example, you can use notepad.exe, which has a GUI, to edit the Apache configuration file to install the certificate. In that case, you don’t need the ACME client to actually install the certificate. It just needs to get a certificate issued.
So therefore my question was: does it actually need to install the certificate or is just getting the certificate with automatic renewal fine?
And the second question was, which wasn’t answered also in your post, which other clients from the ACME client list did you already try besides Certify the web?
