Thank you for your message.
Could you please clarify if you have considered using the MSI configurator tool
in order to help switching your clients from Agent to the Host? This way, you can configure a One-Click package
that will allow you to build a self-extracting Host installer with your custom settings. A remote user will only need to run the file in order to install the Host on their computer and switch from using Agent to Host.
Hope that helps.
