Hi,
Whether you Sign the ClickOnce manifests or not, your client can still deploy your application.
The purpose of signing is to give your client assurance that the application is coming from a valid source.
I assume you are using a self created cert, using self created cert ClickOnce is always going to show the user your application is from an 'Unknown Publisher', no matter how. You will need to pay to get a certificate from a Certificate Authority (CA) to get rid of the 'Unknown Publisher' message.
Below is the related details from MSDN:
"You can use self-certs to deploy ClickOnce applications with high trust on an intranet; however, when these applications run on a client computer, ClickOnce will identify them as coming from an 'Unknown Publisher.' By default, ClickOnce applications signed with self-certs and deployed over the Internet cannot utilize Trusted Application Deployment.
By contrast, if you receive a certificate from a CAsuch as a certificate vendor, or a department within your enterprisethe certificate offers more security for your users. It not only identifies the publisher of the signed software, but it verifies that identity by checking with the CA that signed it."
