Update 3 for Microsoft Visual Studio 2012 was released on June 26, 2013, but installing it is obvious only via Internet-based install. I refuse to perform Internet-based installs for development tools, so that I can retain the ability to recompile my source code 10-20 years in the future, long after update servers have been shut down. Although an ISO for Update 2 was well-advertised, the ISO for Update 3, at this moment, is hidden and difficult to install. Below are the steps.
- Download the Update 3 ISO from the non-advertised link http://go.microsoft.com/fwlink/?LinkId=301705.
- Before executing the install, it may be necessary to update your Microsoft root certificates. This can be done via KB931125. Note that it may be necessary to visit that link twice -- once to give permissions and a second time to actually save/execute the needed rootsupd.exe.
