Microsoft .NET ClickOnce Launch Utility has stopped working

Has anyone ever seen this error message before?

I can‘t find any information about it.  I think it has something to do with this error that I was getting earlier:

<assembly> must be strong signed in order to be marked as a prerequisite

I solved the above error by rebuilding all my references, but now I‘m stuck on this error.  It‘s not tied to my computer, and it doesn‘t have anything to do with dfsvc.exe, because my other ClickOnce apps are working as expected.

Great way to end a week.

Update:  I fixed this error by creating a new .pfx key to sign the ClickOnce application.
