CAD2010还未注册就闪退是怎么回事？

具体解决方法：

1、既然重装无法解决,首先考虑是安装信息残留，

点击开始菜单打开运行,或者用快捷键Win+R，

输入regedit打开注册表编辑器。

2、打开注册表编辑器后，

定位到以下键值ROOT\\installer\\Products\\。

3、找到以7D2F开头的键值,这里有两个都得删除。

4、退出注册表编辑器,再打开一次CAD2010看看，

如果再次出现闪退,那就定位到以下目录，

C:\\Documents and Settings\\All Users\\Application Data\\FLEXnet，

删除此文件adskflex_*_tsf.data,就是软件的注册信息,删除后重置。

5、因为删除注册许可信息后,再一次打开CAD会提示验证许可。

6、出现激活的对话框。

7、然后重新对CAD进行激活就可以恢复使用了。
