问题
I've deployed a ClickOnce application several years ago with the ClickOnce to production. The (purchased) certificate expired a few days ago. I bought a new certificate and I installed it on my machine. I tried to deploy the application, and I see a prompt that warns me about the different key used in the previously deployed application.
I read this in order to solve this problem: Certificate Expiration in ClickOnce Deployment which is not maintained anymore. According to the documentation if I target .NET 4.0 there should be any problem. So I overwrote the previous deployed application and now, in (my test environment) the user is getting "Application cannot be started. Contact the application vendor." and in the details I get this:
Below is a summary of the errors, details of these errors are listed later in the log. * Activation of C:\Users\User\Desktop\Appname.appref-ms| resulted in exception. Following failure messages were detected: + The deployment identity does not match the subscription.
COMPONENT STORE TRANSACTION FAILURE SUMMARY No transaction error was detected.

COMPONENT STORE TRANSACTION DETAILS No transaction information is available.
What should I do in order to avoid this very bad scenario, and how can users update their application without uninstalling the ClickOnce application?
