8.1.7 net8 configuration时报错

8.1.7 net8 configuration时报错

我在7.2上装8.1.7,到了net8 configuration assistant    in progrss
时,就不动了,等了10分钟都没反应,
下面显示done parsing command line arguments net8 configuration.
请各位大佬指教.      
oracle好象很笨哟,它连提示都不给,硬盘一起码在闪!!!!!!
但进度一点也没有变化!!!!!!!!!!!!      
No!
If the process is under installtion,click the "erform typical configuration"!      
还没到Perform typical configuration,就停了,
我删了个400M的文件,重新安装就好了,谢谢大家的帮助。
