With the recent announcement to deprecate the web player we’ve also decided to no longer couple the offline web player with the simulation license it was made for initially.

The installers are available freely at the following links:

• 5.3.x: http://files.unity3d.com/stefan/webplayer/webplayer_archive/ClosedNetworkPlayer_5.3.1f1.zip + http://files.unity3d.com/stefan/webplayer/webplayer_archive/ClosedNetworkPlayer_5.3.2f1.zip + http://files.unity3d.com/stefan/webplayer/webplayer_archive/ClosedNetworkPlayer_5.3.3f1.zip + http://files.unity3d.com/stefan/webplayer/webplayer_archive/ClosedNetworkPlayer_5.3.4f1.zip +
• http://files.unity3d.com/stefan/webplayer/webplayer_archive/ClosedNetworkPlayer_5.3.5f1.zip+http://files.unity3d.com/stefan/webplayer/webplayer_archive/ClosedNetworkPlayer_5.3.6f1.zip +
  http://files.unity3d.com/stefan/webplayer/webplayer_archive/ClosedNetworkPlayer_5.3.7f1.zip + http://files.unity3d.com/stefan/webplayer/webplayer_archive/ClosedNetworkPlayer_5.3.8f1.zip + http://files.unity3d.com/stefan/webplayer/webplayer_archive/ClosedNetworkPlayer_5.3.8f2.zip

• 5.2.x: http://files.unity3d.com/stefan/webplayer/webplayer_archive/ClosedNetworkPlayer_5.2.4f1.zip
• 5.0 to 5.1.4: http://files.unity3d.com/stefan/webplayer/webplayer_archive/ClosedNetworkPlayer_5.1.4f1.zip
• 3.x to 4.7.2: http://files.unity3d.com/stefan/webplayer/webplayer_archive/ClosedNetworkPlayer_4.7.0f1.zip + http://files.unity3d.com/stefan/webplayer/webplayer_archive/ClosedNetworkPlayer_4.7.1f1.zip +
• http://files.unity3d.com/stefan/webplayer/webplayer_archive/ClosedNetworkPlayer_4.7.2f1.zip

The zip archives contain the following installers:

• UnityWebPlayerFull.exe: Normal player which runs in Windows Firefox and IE (both 32bit).
• UnityWebPlayerDevelopment.exe: Development player which runs in Windows Firefox and IE (both 32bit).
• webplayer-x86_64.dmg: Normal player which runs on OSX Firefox and Safari.

These players come with a runtime packaged and don’t need an internet connection to start or run content. They are however limited to this one runtime which has some compatibility implications as listed above.

For example if you have the 4.6.9 player installed you can only run 3.x-4.6.9 content with it. It will not play anything made with 5.0.x or 5.1.x or 5.2.x.
