==== 概要 ====
Zoo 5 需要[[http://www.microsoft.com/en-us/download/details.aspx?id=17718|Microsoft .NET Framework 4]].。你可以藉由[[http://windows.microsoft.com/en-us/windows/windows-update|Windows Update]]确认Microsoft .NET Framework 4 安装在计算机系统中。

=====问题=====
我在2008 R2系统的Windows服务器安装了Zoo 5，但Zoo的服务器无法启动，我在Windows 事件日志里看到以下讯息：

<code>
Service cannot be started. System.IO.FileNotFoundException: Could not load 
file or assembly 'System.ServiceModel.Web, Version=4.0.0.0, 
Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its 
dependencies. The system cannot find the file specified.
File name: 'System.ServiceModel.Web, Version=4.0.0.0, Culture=neutral, 
PublicKeyToken=31bf3856ad364e35'
at ZooService.ZooService.OnStart(String[] args)
at System.ServiceProcess.ServiceBase.ServiceQueuedMainCallback(Object 
state)
</code>

=====解决方法=====
Zoo 5需要完整的[[http://www.microsoft.com/en-us/download/details.aspx?id=17718|Microsoft .NET Framework 4]]。单是安装.NET Framework 4 Client Profile无法让Zoo 5运作。
