I’ve tried this on the latest nightly version and it all works well for me!

1. Start Slicer as administrator: in the start menu, instead of left-click on the Slicer icon, use right-click, then select `More...` and `Run as Administrator`.

2. Install a package by using `pip`. For example, installing of `requests` package:

Enter this into the Python interactor:

```
import pip
pip.main(['install', 'requests'])

```

The package is successfully downloaded and installed:

```

    Uninstalling chardet-2.3.0:

```

Dependent packages are updated, therefore before using the installed `requests` package, you need to restart Slicer (you can use the `restart()` command in the Python console).
