Your other question seems to indicate having a problem using the certificate in VS.

I tried using the original key as the first parameter – no joy, same error.
I tried using the first extended key – no joy, same error.
I tried setting the system time to a previous date where the keys would not already be expired – no joy, same error.
While this is a great learning opportunity, I’ve pretty much run out of ideas. Any others? Thanks in advance.

We now have two certificates which are expiring again after the 5-year window (that we didn’t know we could circumvent). Does this work two times in a row?

I keep getting an error when using renewcert with the parameters exactly as described. The error I receive is not in the command line, but in Visual Studio: when attempting the ClickOnce publish, it fails with the following error: “certificate is not valid for signing”. I’m basically at a loss at this point, especially since I have another program I’ve been asked to handle, which has this same problem (expires on Mar. 20). Any ideas? Thanks in advance!

We were unaware of the issues with the Thawte certificates when we started this project… I asked my corp IT for a code signing certificate, and that was what I was provided. Yes, we found an issue – we basically have to install the certificate on the end-user pc… but at least the ‘renewal’ went smoothly – and the installed certificates updated themselves…. thankfully!

It is not a VS issue, it is a .NET Framework issue. It should be okay in .NET 4. I have to say, though, that I wouldn’t use a Thawte certificate for a VSTO application; Thawte has intermediate certificates and for VSTO applications, it is not recognized correctly.

Try rebuilding it (with the new certificate). I’m not really sure why you need to extend the certificate, as Silverlight doesn’t use ClickOnce, and I believe just needs a valid certificate in order to work?

You have to either publish a new version or create new manifests with Mage or MageUI with a new version number, and copy the new version to your deployment directory.

Next thing you know, it will get all resentful and stop sending the keys you press, so “hello” could be sent as “bite me”, which could seriously impact any communications you have with your upper management. So in the interest of your continued employment, I’m glad I was able to help. ;-)
