SQL Server 2005 x64: Required 64-bit ASP.Net

在64位的Windows Server 2008 R2上安装 Microsoft SQL Server 2005 x64 ，得到下面的警告，如果不需要安装Reporting Service就可以忽略：

"32-bit ASP.Net is Registered. Required 64-bit ASP.Net to install Microsoft Reporting Services 2005(64-bit)."

如果你需要安装Reporting Service就需要执行下面的命令在IIS上启用这些扩展:

cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 1
%SYSTEMROOT%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i
cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 0
%SYSTEMROOT%\Microsoft.NET\Framework64\v2.0.50727\aspnet_regiis.exe -i
