下載 OverbyteIcsV816 完成後解壓到E:\Delphi7\OverbyteIcsV816\
1、在library裡加入E:\Delphi7\OverbyteIcsV816\Source目錄。
2、從File->Open中打開E:\Delphi7\OverbyteIcsV816\Install\D7Install.bpg文件。(文件名在其它Delphi版本略有不同)
3、在項目管理器中,右鍵OverbyteIcsD7Design.bpl選擇Build和Install
64位系統
4、將D:\軟體\Delphi777777\bpl\OverbyteIcsD7Design.bpl
D:\軟體\Delphi777777\bpl\OverbyteIcsD7Run.bpl
拷貝到 C:\Windows\SysWOW64下
就安裝完成了!
