Can't install PostgreSQL: An error occurred executing the Microsoft VC++ runtime installer on Windows XP

One of the reasons this can happen is because the installer attempts to install an older version of the VC++ runtime than what you are currently using.

See this installation log, found in your user's temporary directory (e.g. dd_vcredist_amd64_20190214193107.log):

[20C0:20E4][2019-02-14T19:31:07]e000: Error 0x80070666: Cannot install a product when a newer version is installed.

A workaround is to prevent the runtimes from installing with the --install_runtimes option:

postgresql-9.6.12-1-windows-x64.exe --install_runtimes 0

  1. Create a shortcut of the downloaded file:

  2. Right click of the shortcut → PropertiesShortcut. Add --install_runtimes 0 to the end of the file path:

  • Create a shortcut of your EXE file;
  • right click on the shortcut → add --install_runtimes 0 at the end of the target path, e.g.:

    postgresql-9.3.1-1-windows-x64.exe --install_runtimes 0
    
  • save and run it :)
