Install:
Following on from the last screen shot in the prvious post. The next window should look like this.

Click on the Agree button. Failure to do so will result in termination of installation.
This should then give you the Options screen.

If a new user it is recommended to leave this as default (both boxes are checked). In my screen shot you can see I have opted not to have a Desktop Icon.
Click the Next button.
This screen simply asks for confirmation of install. Just click the Install button.

On completion this screen should be present. Just click the Close button.
