Pandas not installing in 64 bit windows

Question

I recently installed a new verion of Anaconda 3 4.2 on a windows laptop. All the packages work fine , but pandas never worked for me from day 1. So i thought of uninstalling and installing a new version of pandas 0.19

While using pip:
C:\Users\>python -m pip install --user pandas
Collecting pandas
  Using cached pandas-0.19.2-cp35-cp35m-win_amd64.whl
Exception:

Answer 1

Try to use Anaconda package manager - conda instead of pip:

C:\> conda install pandas

Answer 2

The problem is that you are trying to install Pandas as a regular user, and therefore cannot change the contents of Anaconda installation folder (where Python installed packages live). You need to run CMD or PowerShell (whichever you are using) as an administrator. Right-click on its shortcut in the start menu and click "Run as administrator", then run again the same command.
