Answer 1

原因：电脑系统残留着其他版本CAD的文件。

1、首先按“win+R”组合键打开运行，点击输入“REGEDIT”，回车确定。

2、然后在弹出来的窗口中点击打开HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer中的Patches项。

3、然后在弹出来的窗口中删除7D2F387510074080002000060BECB6AB键值，这记录的是Autocad的安装源路径，点击这个键值可以看到右边显示的信息正是Autocad的安装信息。

4、然后删除HKEY_LOCAL_MACHINE/SOFTWARE/Autodesk/AutoCAD和HKEY_LOCAL_user/SOFTWARE/Autodesk/AutoCAD。

5、然后就可以正常安装了。

你的windows7没有打Net Framework的补丁，需要用windows up data更新系统，所有和Net Framework 有关的补丁都打上就可以了（可选补丁也要打），我的也是这个情况，更新好就可以用了，360等各类管家都会忽略各种补丁，建议使用Windows UPdata。本回答被提问者和网友采纳
