After I reinstalled windows my clickonce signing does not work anymore. Clicking publish gives me a pop up saying:

"The application is signed with a different key than the existing application on the server. Do you want to overwrite it?"

According to the MS Help clicking yes will cause my users to stop getting automatic updates. I also got a warning about the culture settings but after setting en this is checked and cannot be the problem. I found a similar problem but without a helping answer to solve it. Could anyone help me here?

Solution: It was a problem with the certificates expiring date.

Solution: I downloaded the renewCert Tool from here. Be carefully, you have to use the project as a zip file link and compile it yourself. For this to run you have to add Crypt32.dll to Project->Properties->Linker->Input->Additional Dependencies for Configuration: Release.

Now I used the command line to extend my certificates expiring date. Now it works.
