I have struggeled for over a month with trying to install Visual Studio 2015. At first I tried the MSDN forums for help, but go nowhere. I finally resorted to format my system drive and reinstall the operating system (Windows 10). Then I got it to work, for some time. Then suddenly it was broken again. Neither repair nor uninstall/install helps. I still get the same error during installation, i.e. fatal error during install of team explorer.
Other users on the MSDN forum seem to have the exact same problem. No solution, other than reinstall the OS seems to help.
Could someone try to fix this? Or at least make the team explorer component optional?
