（Web Api服务）当前标识没有写访问权限

Question

我有Win 8.1 Enterprise和Web Api编程的Web服务 我将其作为网站部署到IIS

在浏览器中调用“localhost：9810 / api / person”url时显示以下错误

The current identity (IIS APPPOOL\PersonService) does not have write access to 
'C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files'.

我该如何解决这个问题？ （需要一步一步的指导！）

更新：

我在调用http：// localhost /

时安装了所有IIS，.NET 3.5，.NET 4.5功能

浏览器显示此错误!!!为什么？!!!

The current identity (IIS APPPOOL\DefaultAppPool) does not have write access to 
'C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files'.

和通话时（作为管理员）

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Aspnet_regiis.exe 

CMD说：
