  • Hi Joy,

    Welcome to the MSDN Forum.

    Based on the error message, it used this certificate "C:\Users\Administrator\Documents\GitHub\SPLink2010\SharePoint_Link\ITOPIA_certificate2.p12"

    So would you like to replace this certificate with your new one, rather than just import it to System.

    I hope this will be helpful.

    Best regards,

  • Hi Joy,

    You are welcome.

    Which options do you check?

    Sign the clickonce manifests?

    Sign the assembly?

    Delay sign only?

    And it still report "C:\Users\Administrator\Documents\GitHub\SPLink2010\SharePoint_Link\ITOPIA_certificate2.p12" is not valid?
