使用VS2003 自带的installer 遇到奇怪的问题!高分请高手解答,很快结帖!!

[showmetoyou]

小弟第一次做installer,在我的项目部署中要实现自定义安装程序时,如果检测到旧版本,弹出对话框,删除旧版本,接着安装项目!这些功能通过自定义install类的override install方法已经实现,主输出设置为自定义install类库,
但效果如下:
1.双击setup.exe-->进入vs2003 installer 默认的welcome页面--进入vs2003installer 默认的installation Folder页面-->执行安装---弹出检测到旧版本对话框--.....

问题是我要实现像金山词霸那种效果,首先就弹出检测到旧版本对话框!感觉override install 事件是在那些默认页面之后,拷贝文件执行安装之前才执行!
请问高手怎么实现如下效果啊?

BeforeInstall我也用过,效果一样的!
因为Install,beforeInstall都是在真正安装时才触发的,自带的欢迎form,选择路径form都没有触发事件!

大家怎么看呢?

[bigrongshu]

确实OnBeforeInstall是在真正安装时才触发的，刚看了这个贴

http://www.mcse.ms/message1066083.html

建议楼主转其他安装工具解决这个问题

[bigrongshu]

检测应该在BeforeInstall里面，不是Install里面

// Override the 'OnBeforeInstall' method.
protected override void OnBeforeInstall(IDictionary savedState)
{
base.OnBeforeInstall(savedState);

// Add steps to be done before the installation starts.
Console.WriteLine("OnBeforeInstall method of MyInstaller called");
}
