下载 OverbyteIcsV816 完成后解压到E:\Delphi7\OverbyteIcsV816\
1、在library里加入E:\Delphi7\OverbyteIcsV816\Source目录。
2、从File->Open中打开E:\Delphi7\OverbyteIcsV816\Install\D7Install.bpg文件。(文件名在其它Delphi版本略有不同)
3、在项目管理器中，右键OverbyteIcsD7Design.bpl选择Build和Install---要把BPL输出目录也加入 1、在library里
64位系统
4、将D:\软件\Delphi777777\bpl\OverbyteIcsD7Design.bpl
D:\软件\Delphi777777\bpl\OverbyteIcsD7Run.bpl
拷贝到 C:\Windows\SysWOW64下
5、E:\Delphi7\OverbyteIcsV816\Packages\OverbyteIcsD7Design.dpk可视化组件
就安装完成了！
