Unity Engine Version Download

Is there a place to download an install file for the Unity engine version? When I go to http://unity3d.com/unity/download/ I install that file but it installs only the web player version. I have a laptop that I cannot connect to the internet that needs the latest engine version. For my computer I am able to get the latest engine version by installing that file and then running some unity content which then connects to the internet to get the latest engine version. This will not work on the laptop that is not permitted to connect to the internet. Please let me know what I can do.

Start Your Creative Projects and Download the Unity Hub | Unity for the 3.5 beta.

To update the engine version manually you have to use the full install link: http://webplayer.unity3d.com/download_webplayer-3.x/UnityWebPlayerFull.exe
