请教D7下如何安装Virtual Treeview
我在Virtual Treeview官网： http://www.soft-gems.net/supplement/download.php?ID=28下载了VirtualTreeViewV5.0.0，按照http://blog.csdn.net/akof1314/article/details/6449889所说的方法安装“将".../Source"和".../Common"路径添加到"Environment Options"下的"Library"里”但安装包中没有Common这个文件夹。不设置Common这个路径，同下面一样还是报错

按照所下载的安装程序中所说的：

Delphi 7 Installation
~~~~~~~~~~~~~~~~~~~~~
1. Open the project group "Packages\Delphi 7\VirtualTrees.bpg"
2. Right click on "VirtualTreesD" and click "Install"
3. Go to "Tools > Environment Options > Library > Library Path > [...]"
Browse to the "Source" folder of VirtualTreeView, press "OK", "Add", "OK", "OK"
——————————————————————————————————————————
打开\VirtualTrees.bpg 后 view-> projectgouup management
Right click on "VirtualTreesD" and click "Install"报“没有找到virtualtreesR.bpl,因为这个应用程序未能启动。重新安装应用程序可能会修复此问题”。

总是装不成功，请教这个控件的详细安装方法

[解决办法]
virtualtreesR.bpl 放在project\bpl目录下
[解决办法]
先卸载掉重装吧，Component->Install Packages->找到Virtual Tree->Remove;把Projects\Bpl里面对应的bpl也删除掉
安装:
1.打开\Packages\Delphi 7\VirtualTrees.bpg
2.VirtualTreesR是运行时包，按右键点编译(compile)即可;
VirtualTreesD是设计时包，按右键先选择Options->Description->Usage Options->选Designtime only; OK确定退出,再按右键点安(Install)
3.添加Source路径
