  • Right-click the file and click Properties. At the bottom of the Properties sheet, click Unblock.

Testing the Python Installation

If python won't launch, you can fix it with an Administrator Command Prompt window.

Click Start (on Windows 8, press the Windows Logo key on your keyboard) and type this search term:

When Windows finds "Command Prompt", right-click it and click "Run as administrator".

If a "User Account Control" box appears, click Yes.

In the Administrator Command Prompt window, execute these commands, as shown below.
