Updating certificate details at the clients machine

Hi,

I signed my C# console application with signtool.exe. Valid period for my certificate is 1.1.2014-1.1.2016. The application was sold to the end user, whichhas no internet connection and UAC, on his win7x64, is on.

At 1.1.2016 i renew my certificate, how the user will receive the certificate with a new valid period? I want to prevent the 'yellow' UAC prompt.

Do i need to send the patch or something else?

Thanks
