1.必须配套安装XP Theme Manager、ExpressLibrary、ExpressExport Library、ExpressDataController、ExpressEditors Library 5和ExpressPageControl 2，已经安装过的则跳过；
2.在Delphi 7中，选择菜单File | Close All（最好这样）；
3.选择菜单Tools | Environment Options...，在Environment Variables页中，点击"New..."按钮，在Variable Name右边输入框中输入cxQGrid（或任意其他名字，但后面的设置要与此一致），在Variable Value右边输入框中输入DevExpress.ExpressQuantumGrid.Suite.v5.9的绝对路径（也就是你把DevExpress.ExpressQuantumGrid.Suite.v5.9包解压到什么目录，例如：D:/VCLPackages/DevExpress_ExpressQuantumGrid_Suite_v5.9/），按"OK"；
4.点击"Library"切换到Library页，在Library path后面加上：
$(cxQGrid)/XP Theme Manager/Sources;
$(cxQGrid)/ExpressLibrary/Sources;
$(cxQGrid)/ExpressExport Library/Sources;
$(cxQGrid)/ExpressDataController/Sources;
$(cxQGrid)/ExpressEditors Library 5/Sources;
$(cxQGrid)/ExpressPageControl 2/Sources;
$(cxQGrid)/ExpressQuantumGrid 5/Sources;
