AO开发问题！

 
<P>我安装了ARCGIS9.2，可是在VS2005中加入MAPCONTROL和Pagelayout时，在控件里面提示</P>
<P>ArcGIS Engine Mapcontrol</P>
<P>Name:AxMapControl1</P>
<P>warning:the LicenseControl is not used to initialize this application with a license.Please add the LicenseControl or programmatically use the AoInitialize object to initialize this application.</P>

大哥，能不能说清楚点啊,。我没装Arcengine，装的是ArcGis Desktop.
