为什么安装完delphi2007后建立一个工程运行出现错误？<br>下面是错误的信息．<br>[MSBuild Error] The "DCC" task failed unexpectedly.<br>System.Configuration.ConfigurationErrorsException: Configuration system failed to initialize ---&gt; System.Configuration.ConfigurationErrorsException: Unrecognized configuration section startup.

高手都不在吗？分少了吗？不知道那位大虾也遇见过这样的问题，告诉小弟一声．小弟刚刚学习delphi所以有很多不明白的，请大虾门帮个忙，还是太难了，我先自己顶下~~~

还是没人呀，分不够吗？不够我可以在加100．在线等~~~

偶没装过，不过貌似看到有人说要关掉ide重开，才能正确，<br>如果还有错误，卸载赶紧，重新安装了
