It sadly is a bit of a click fest to get the download installed. First it warns you to not save the download. Next up you get the warning from the screenshot Then you get the normal UAC prompt that shows your company details. After that the installer itself comes up. I think I even am forgetting a click. It is a pretty unpleasant install experience. Another developer told me that you might be able to cure this by buying an EV certificate instead. Yet another one said that the company he works for (pretty well known) has the same issue. Of course I already bought a normal multi-year certificate which wasn't cheap. So now I would have to throw that away and buy an EV certificate? Which are even more expensive and don't really offer more security beyond the "it's more expensive" limit.
