卸载: 

1. Remove the package from Install Packages menu 

从Delphi的IDE中卸载Indy组件包 


2. Delete the *.BPL and *.DCP files of Indy from the installation directoy and from your System folder 

从你的系统目录中删除以Indy开头的所有bpl和dcp文件 


3. Remove any old old Indy files from your library path 

从你的Delphi的Library path中删除所有Indy的路径 

4。安装你的新Indy组件 



安装很顺利（安装前请先卸载Delphi自带的Indy），不过加载项目进行编译的时候报错： 

[Fatal Error] Unit1.pas(11): Unit IdContext was compiled with a different version of IdSocketHandle.TIdSocketHandle 



解决方法也很简单：只要把下列路径（默认安装在C:\Program Files\Indy 10 for Delphi 7）加入Delphi的 Library Path即可。 

C:\Program Files\Indy 10 for Delphi 7\Source\Core 

C:\Program Files\Indy 10 for Delphi 7\Source\Protocols 

C:\Program Files\Indy 10 for Delphi 7\Source\SuperCore 

C:\Program Files\Indy 10 for Delphi 7\Source\System
