我安装的是电驴中下载的3CD的wincc flexible 2005的软件，安装时一切正常。可是安装完后当我点击wincc flexible时会提示如下文字：
wincc flexible 2005 standard cannot establish connection to the automation license manager service.the application will be closed.
possible reasons:-the required version of automation license manager is not installed.
-the service startup did not complete before wincc flexible 2005 standard was launched.
-the service has been terminated.
但是当我再安装automation license manager时却提示我there are date on your computer which will be delected next time you restar the computer
this may lead to problems if you reinstall the software
restar windows and then star setup again.然后不能继续下一步，因为下一步是灰色的。
我的问题就是这是什么赞成的呀？在什么情况下安装不会有问题呀？请大家帮提示一下。谢谢了。
