我安装CAD出现错误了啊。 装cad2008出现错误1606....估计你是win7的系统，一般来说win7装2009以下的cad都会出状况，建议你别装2008了，试试高点的版本吧。如果非要装2008，试试以下的办法：

安装cad错误1606怎么解决 解决安装cad出现1、可能原因：文件解压出现破损文件。电脑老的CAD程序相关文件没有卸载干净，（卸载时没有进行清扫）。
2、解决方法: 打开注册表:regedit HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerUser Shell Folders 从右侧窗口 找到“%allusersprofile%start menuprogramsstartup”所在的注册表项， 更改为“C:Documents and SettingsAll Users“开始”菜单程序启动”。

CAD2010安装过程中总是出现“错误1606，无法访问网...原因：安装程序的注册表参数设置不正确。
1、首先打开电脑桌面左下角的开始菜单栏，选择打开“运行”。
2、然后在弹出来的窗口中点击输入“regedit”，回车确定。
3、然后在弹出来的窗口中点击找到HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorer中的User
Shell Folders项。
4、然后在弹出来的窗口中右键单击“Common AppData”，选择“修改”。
5、然后将数值数据更改为“%ProgramData%”，回车确定。
6、然后就可以安装CAD了。
