I am having the same problem everyone else is when installing Visual Studio 2015 with Update 1. It is failing on the Team Explorer install and as far as I can tell it is bei
Success! Easy to try, anyway.
I had similar problems and tried re-installing several times, but no joy. I was looking at installing individual packages from the ISO - not happy at all.
I finally got it to "install" by simply selecting "repair" rather than "uninstall" in control panel / programs. It took quite a while to do the "repair" though. In the end it is installed and working.
This may help some.
