加载驱动时出现的问题
我最近在学一些关于驱动方面的知识，但有一个问题老是解决不了代码如下
这是一段加载驱动的代码，我在我的64位CPU,64位win7系统下老下运行出错，但在32位系统上或32位cpu配64位win7却能正常运行，上面出错原因是
StartService faild() 2！这好像是路径问题，但是我的路径可以很确定没有问题的，有没有高人帮我看下哪里出问题了

谢谢了。 win7 64位 驱动加载 驱动开发
[解决办法]
参考http://stackoverflow.com/questions/13545675/startservice-and-sc-start-return-error-file-not-found
When it's running in WOW64 it goes to Windows\SysWOW64 not system32.
Once I copied the 32 bit Service .exe into Windows\SysWOW64 and ran it the Service started!
[解决办法]
在64位Windows下：
64位exe和dll在目录c:\windows\system32目录下；
32位exe和dll在目录c:\windows\syswow64目录下；
