Was a different F-Secure product, or 3rd party Antivirus ever installed on this machine ?
Proceed to check if you can find any information in the server's Event Viewer (application) that indicates this installation error. As an example:
The Windows MSI installer error code 1625 translates to "This installation is forbidden by system policy. Contact your system administrator." You can refer to the Microsoft documentation for the list of MSI error codes.
You can refer to the Microsoft TechNet portal on a list of workaround available to fix this installation error.
This error indicates that either F-Secure Computer Protection or F-Secure Client Security 14.xx has been previously installed on the computer. The uninstallation of the previous F-Secure product has left some leftover files on the computer which are conflicting with the new installation.

Thanks Jamesch for the response.
But the machine had no prior antivirus installed on it. It was running on windows 8.1 and using windows defender as the only antivirus. But anyway, I think something probably on the machine was preventing the complete installation of the antivirus, either a malware that could have compromised the computer registry, which might lead to deny new registration of the F-secure antivirus on it.
We have agreed with the client to do a clean installation of the operating system then run the antivirus again.
Thanks once again community for the responses.
one thing to verify is that you have run windows update check on this computer. This error might be caused by the fact that the operating system has too old SSL root certificates and therefore the installer cannot do HTTPS communication to F-Secure backend servers.
