The log says "Error 0x80070570: Failed to extract all files from
container, erf: 1:4:0". 0x80070570 is a failure code for the Windows
API (facility code 7) with the error value ERROR_FILE_CORRUPT
(0x0570). The simplest recourse at this point is to clear the browser
cache and download the installer again.

Here's a program from Microsoft to check MD5 sums. You can copy
fciv.exe to the Windows directory.

Then verify that the MD5 sum is 4d6fdb5c3630cf60d457c9825f69b4d7, as
posted on python.org:

    >fciv python-3.5.1.exe
    //
    // File Checksum Integrity Verifier version 2.05.
    //
    4d6fdb5c3630cf60d457c9825f69b4d7 python-3.5.1.exe

Of course, the file could be fine and this error could be just a
symptom of another problem.
