ClickOnce Setup instantly stops executing

Question

I've got a problem with a ClickOnce Setup and have absolutely no idea what I'm doing wrong...

I'm trying to publish a VSTO AddIn for Outlook 2013 using VS2012. However when I click on the Setup.exe created by the ClickOnce Publish the Setup shows the small installation window for about half a second and then instantly disappears again. This without showing any error message or generating any event log entries at all.

• The ClickOnce manifest is signed with a test certificate (self-signed certificate).
• The assembly is not signed. (However if I choose to sign it, nothing changes)
• I'm publishing to the filesystem using CD or DVD-ROM as installation path (publishing to IIS results in the same problem)

Yesterday this had worked. Today it won't. Hadn't changed anything since then...

Has anyone an idea what I might be doing wrong?

Answer 1

Finally found the answer... After many tries to reproduce the problem i noticed the following:

If I create a new project don't change anything but create manually a test certificate the published setup won't run, but if I don't change anything at all it works...

As ClickOnce creates a Certificate for signing the manifest I started comparing the differences between those certificates. Comes out: the hash algorithm has to be sha1

This certificate doesn't work. And the installer will abort without giving an hint about what's wrong:

This certificate works.

One might think that the Setup would give at least a hint about what might be wrong instead of just aborting.

I hope if someone else stumbles upon this issue this might help :)
