Visual Studio 2015 installation fails at Team Explorer

Question

Trying to install VS2015, but I get this error every single time:

[I can't currently post links or images. See https://social.msdn.microsoft.com/Forums/getfile/768724 ]

I have tried some of the fixes from previous occurrences of this:

• The "fsutil behaviour set SymlinkEvaluation L2L:1 L2R:1 R2L:1 R2R:1" fix (Suggested Here: [https://social.msdn.microsoft.com/Forums/vstudio/en-US/0e099960-7be0-45a3-b183-61cd560960d6/visual-studio-2015-install-fails-team-explorer-language-pack-enu-fatal-error-during?forum=vssetup])
• Installing using ISO
• Tried Installation Repair
• Tried manually re-installing The Visual C++ Redistributables for VS2015 (Suggested here: https://social.msdn.microsoft.com/Forums/en-US/07604354-e8f8-41ad-8cc8-c080f8feb3ce/visual-studio-2015-installation-fails-at-team-explorer-module?forum=vssetup)
• Disabling Windows Defender and Firewall
• The SHA-1 checksum posted here (https://www.visualstudio.com/en-us/visual-studio-2015-iso-sha1-vs) doesn't seem to match what I download here (https://www.microsoft.com/en-us/download/details.aspx?id=48146). Why the SHA-1 values aren't the same webpage is a mystery, but I get the same checksum each time I download the ISO, so I doubt it's a corrupt file issue. I also checked the online installer I downloaded multiple times, the checksums are all identical.

Here is the log of my last attempt (https://onedrive.live.com/redir?resid=9169DD61E8C86CD!1640&authkey=!AJPpwvpJOgyiq8Q&ithint=file%2clog).

Anything else I can try?

Hi Sebastien,

Thank you for posting in MSDN forum.

I checked the log file you uploaded and found several error message below: 

[13EC:0DDC][2015-12-15T11:38:36]i000: MUX:  ExecuteError: Package (nugetvs) failed: Error Message Id: 1722 ErrorMessage: There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor.

It means that your installer package is corrupted, so you need to re-download a healthy VS iso image.

VS 2015 iso Microsoft official download link:

https://www.visualstudio.com/en-us/downloads/download-visual-studio-vs.aspx

VS 2015 iso files SHA-1 Values link:

https://www.visualstudio.com/en-us/downloads/visual-studio-2015-iso-sha1-vs.aspx

PS: To make sure whether your package is corrupted or not,

please use FCIV.exe http://support.microsoft.com/kb/841290  to verify hash of the ISO.

Any discrepancy would indicate that the file was corrupted. Here is a blog for how to use it, you can refer to it.

              
Besides, in order to narrow down the problems of VS setup, there are some tips about installing VS:

1. Disable anti-virus or anti-spyware software.
2. Check windows update.
3. Clear %TEMP% folder.
4. Run the installer as administrator.

you should make sure you’ve followed these tips:  http://social.msdn.microsoft.com/Forums/en/vssetup/thread/60f71a54-506e-4c70-be98-e993ce6d1ddf

Answer 2

Had the same issue.

Problem here was that my (newly installed) machine was running windows updates in the background.

Visual Studio isn't happy with parallel installations, so I assume that killed the installation initially, although Visual Studio seemed to be partially installed (but corrupt).

Solution was to remove Visual Studio from the configuration screen -> Add Remove/Programs and then restart the installation.
