If you've been unable to start the installer or your computer freezes when you try to launch the installer attempt to install using the steps below. They worked for me.
1. Browse to the location where you saved the installer.
2. Right click the installer, choose "Properties".
3. In the properties window at the bottom of the general tab click "Unblock".
4. Click "OK" to close the properties window.
5. Right click the installer, choose "Run as administrator..."
