New submission from Roger Cook:
The Windows installer stops the installation and backs out on a clean system.
Here is the relevant section of the log file (msiexec /i
python-2.7.11.amd64.msi /l*v):

--- end log ---
It appears that the installer tries to call the Python executable before it has
been put in place. This fails, and the installer backs out.
Workaround: Install 2.7.10, then install 2.7.11 over it.
