Cannot install Zabbix via MSI with CONF option

[Ox11]

I am trying to install Zabbix on a windows machine using the msi. I have a custom config file I want to use and have tried using the CONF option. However, this does not work. Has anyone else experienced this issue and able to solve it?
The command I am trying to run is:
msiexec /i "c:\zabbix_agent2-6.4.5-windows-amd64-openssl.msi CONF=C:\Program Files\Zabbixzabbix_agent2.conf"

msiexec /i "c:\zabbix_agent2-6.4.5-windows-amd64-openssl.msi" CONF="C:\Program Files\Zabbix\zabbix_agent2.conf"
