win7下安装virtual box后启动报错

win7下安装virtual box后启动, 报错, 如下

Failed to instantiate CLSID_VirtualBox w/ IVirtualBox, but CLSID_VirtualBox w/ IUnknown works.
PSDispatch looks fine. Weird.

返回代码: E_NOINTERFACE (0x80004002)
组件: VirtualBoxClientWrap
界面: IVirtualBoxClient {d2937a8e-cb8d-4382-90ba-b7da78a74573}

解决办法：
在注册表（开始-运行-regedit）里面进行修改
HKEY_CLASSES_ROOTCLSID{00020420-0000-0000-C000-000000000046}
默认 修改为 C:WindowsSystem32oleaut32.dll
InprocServer32 修改为C:WindowsSystem32oleaut32.dll

HKEY_CLASSES_ROOTCLSID{00020424-0000-0000-C000-000000000046}
默认 修改为 C:WindowsSystem32oleaut32.dll
InprocServer32 修改为 C:WindowsSystem32oleaut32.dll

其实就是oleaut32.dll的路径, 注意自己电脑中的system是大写还是小写
