what happens when a digital certificate expires

[BillE]

I think I'm forced to digitally sign my ClickOnce manifest and assembly for
a windows forms application (see yesterday's post, 'click once deployment
cannot continue'.

This seems like a stupid question, but in all the articles I've read, I
can't find what happens to a user when the digital certificate expires.

Does the application just fail?
Am i going to be scrambling to acquire a new certificate and publish updates
signed with the new certificate?
Will the application automatically update to the new version with the new
certificate, once it is published?

I don't know, but I suspect it would fail at some point, because it
doesn't have a valid certificate.

I thought certificates were at the machine level. So it seems that the
user's workstation must be updated manually by the user.
