求救,DevExpress控件包问题,ExpressEditorsLibrary 5.17中的控件与dxNavBar控件冲突问题(50分)

求救,DevExpress控件包问题,ExpressEditorsLibrary 5.17中的控件与dxNavBar控件有冲突:
这两组控件都是在Delphi盒子上下载的
如果先装了dxNavBar控件,再装ExpressEditorsLibrary5.17的包装不进,错误提示:
Package c:/program files/borland/delphi7/projects/bpl/dxThemeD7.bpl can't be installed because another package with the same base name is already loaded(C:/WINDOWS/System32/dxThemeD7.bpl)
如果先装ExpressEditorsLibrary5.17的包装,再装dxNavBar控件,则加载ExpressEditorsLibrary5.17包中的控件,编译时出错,提示:

[Error] cxScrollBar.pas(886): Incompatible types: 'Integer' and 'PRect'
[Error] cxScrollBar.pas(886): Incompatible types: 'Integer' and 'tagSIZE'
[Error] cxScrollBar.pas(889): Incompatible types: 'Integer' and 'PRect'
[Error] cxScrollBar.pas(889): Incompatible types: 'Integer' and 'tagSIZE'
[Fatal Error] cxLookAndFeels.pas(201): Could not compile used unit 'cxScrollBar.pas'

有谁能解决吗? 能解决此问题另开帖给分300分
