当打开Infopath表单，出现如下错误信息的时候，表明Server State Service未安装：

The form cannot be rendered. This may be due to a misconfiguration of the Microsoft SharePoint Server State Service. For more information, contact your server administrator.

运行Powershell

Add-PSSnapin "Microsoft.SharePoint.Powershell" 

$serviceApp = New-SPStateServiceApplication -Name “State Service”

#Create a State Service database and associate it with a service application
New-SPStateServiceDatabase -Name “StateServiceDatabase” -ServiceApplication $serviceApp

#Create a State Service Application Proxy and associate it with the service application
New-SPStateServiceApplicationProxy -Name “State Service” -ServiceApplication $serviceApp -DefaultProxyGroup

查阅所有的State Service
