title: Clickonce does not run
body: <p>I have found several forum posts about "clickonce does not run/start/install" but none is like my problem.</p>
  
  <p>I'm using ClickOnce for several projects and they work fine. I'm trying to install on a pc but for an unknown reason : nothing. I mean, I launch the "setup.exe" (using firefox), it opens Internet Explorer with the link of the .application file (it's deployed on the web), then IE closes and nothing else.</p>
  
  <p>I tried on two others computer and the setup.exe launchs the installation of the application.</p>
  
  <p>I tried to reinstall the .Net Framework but same thing happens, I disabled Avast and the Firewall, same thing.</p>
  
  <p>How can I fix this, or fins out why it is happening?</p>
