64bit系统运行32位Web程序出现错误：An attempt was made to load a program with an incorrect format

C#写的Asp.Net Web应用程序，本机（32bit）测试正常，发布到64bit系统上（Windows 2008 r2）出现以下错误：

“An attempt was made to load a program with an incorrect format”

解决办法：IIS中选中相应的应用程序池—>Advanced Setting—>Enable 32-bit Applications 改成True 就行了
