今天安装了WinCC V6.2，发现我以前用Delphi编写的一个OPC客户程序连不上OPCServer.WinCC了（以前用的是WinCC 6.0），我用OPC Scout连OPCServer.WinCC也连不上，对话框提示：

类不支持自动化或不支持期望的接口 &H1AE
-Chick, that the OPC-Server component in the Station Configuration Editor is in RUN state!
-Can be caused by a mal funtioning InProc Server
-check, that your server really starts!
-check with DCOMCNFG that all entries for 'OPC.SimaticWinCC' are set up properly, especially PATHNAMES and USERRIGHTs!
-check your Sercerinstallation!


不知怎么解决？
