Instalacja Flaska pod Windowsem

Witam, próbuję zainstalować obsługę Flaska pod Windowsem jednak po komendzie: pip install Flask, w pewnym momencie wiersz poleceń wyrzuca:

Exception:

Proszę o wskazówki jak rozwiązać ten problem.

Odpal pipa z poziomu administratora, albo zmień katalog instalacyjny.
