Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine

在做excel2007 导入时，报的错：“Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine”；

细察下来，是我操作系统为64bit所致。具体方法如下：

“Actually it is because you are running 64-bit windows and there are no MS Access drivers that run 64-bit. So to solve it you need to change your build configuration to x86. You can do that on the project properties dialog under "Compile>Advanced Compile Options...>Target CPU". Change it to "x86". Then clean and rebuild your solution. It should work like a charm now.”
