在執行Register-SPWorkflowService時發生以下錯誤:
The remote server returned an error: (404) Not Found

以下是我troubleshooting的步驟:
1. 用下列cmdlet來確認workflow site的port
 Get-WFFarm | ft HttpPort
 Get-WFFarm | ft HttpsPort
然後以管理員身份在本機開啟連結看看能不能成功開啟
第一次失敗，因為我忘了配DisableLoopbackCheck (http://my007fff.pixnet.net/blog/post/15793123)

2. 檢查config:
 <ScopeInfo xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.microsoft.com/workflow/2012/xaml/activities">
   <ChildScopeCount>1</ChildScopeCount>
   <DefaultWorkflowConfiguration />
   <Description>RootScope</Description>
   <LastModified>2013-11-04T12:03:24.64</LastModified>
   <LastRevised>2013-11-04T12:03:24.64</LastRevised>
   <Path>/</Path>
   <SecurityConfigurations>
   <ScopedSecurityConfiguration i:type="WindowsSecurityConfiguration">
   <Name>Microsoft.Workflow.Management.Security.WindowsSecurityConfiguration</Name>
   <WorkflowAdminGroupName>BUILTIN\Administrators</WorkflowAdminGroupName>
   </ScopedSecurityConfiguration>
   </SecurityConfigurations>
   <Status>Active</Status>
 </SecurityConfigurations>
 <Status>Active</Status>
 </ScopeInfo>

3. cmdlet加兩個參數: Register-SPWorkflowService with -AllowOAuthHttp -Force
