Error while running python and installing packages

Wonder if it is the same issue as this user:

Pip installation issue

Hello Paul, I identified the issue by re-installing the python twice. Previously I used to only install for a single user that too by using the default setup, where some of the features are not installing. So, I installed by manually selecting all the features and for all the users. As already pip was installed, as soon as the python installation has completed successfully, pip went also worked. Thank you, Paul!!

Refer to this thread and uninstall and reinstall as this user has via the instructions given. Can you give this a try?
