In a previous post I described a problem I’ve been having with external links in Visual Studio not working under Windows 8. The problem only occurred when I started Visual Studio with administrator privileges and had Chrome set as my default browser.
It turned out that this problem was related to the way Chrome registers itself in Windows 8 during install. It also affects launching Chrome from any application run as an administrator (not only Visual Studio). The issue (and an more in-depth description of the problem) can be found here.
In short this problem is fixed if you perform a machine-wide install of Chrome (instead of installing for the current user only). This will be the default in future versions of Chrome on Windows 8, and is already implemented in the development version of Chrome. In order to fix this problem on your own machine today, uninstall Chrome, and re-install it from the dev channel (http://www.chromium.org/getting-involved/dev-channel).
