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：
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
