This project allows you to "renew" your existing ClickOnce certificate and give it a longer expiry date. It extends Click Once Certs By 105 years!!!
This code was originally provided by Microsoft and then modified by Cliff Stanford who updated it to add 5 years to the expiry date.
Then Nathan Jones Ported the C++ code to C#.

I have created this project on Github and also extended the expiry date by 105 years.
Fully tested and confirmed it works.
