When I click on the big download icon on codeplex, my IE suggest to download and run the msi.
but once it is downloaded, IE shows me an error windows say "The signature of StyleCop-4.7.42.0.msi is corrupt or invalid"

I can download the msi, and then run it from the desktop by-passing IE but it does look pretty nasty, and I cant help but notice that the setup program isn't signed. wonder if this is related.
