附命令行下卸載和安裝asp.net：
1. Open a command prompt
2. Stop IIS:「iisreset/stop」
3. Change to the .NET Framework 2.0 root directory:「C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727」
4. Stop web services: "net stop w3svc"
5. Uninstall all instances of ASP.NET from IIS: "aspnet_regiis.exe -ua"
6. Reinstall ASP.NET into IIS: "aspnet_regiis.exe -i"
7. Restart web services:「net start w3svc」
如果還不行請將C:\WINDOWS\Temp資料夾改為共用權限EVERONE
