Microsoft Access Error Downloading Sample Data Northwind

Hello,
I just installed Microsoft Access on my computer. I tried to use a sample data provided so I don't have to create one. But I have to download the sample data first before I can use it since it was not packed with the installer.
The sample data that I want to download is Northwind Sample Database, but I don't succeed with it. What is wrong with my installation? Here are some screen captures.
1. Downloading
2. Workgroup Administrator couldn't create the workgroup information file…
3. Microsoft Access couldn't find file ' ': This file is required for startup.
