因为现在xp还是很多用户的，很多初学者在安装arcgis还是会有一些基本的问题出现。在WinXp sp2安装ArcGIS9,会出现动态库注册失败问题，以下是修改办法。
1. 移除Windows XP的SP2，然后安装ARCGIS 9.0。
2. 点击“我的电脑”，选择“属性”菜单 
3. 点击“高级”页。选择“启动与恢复”下的“设置”按钮。 
4. 选择默认操作系统，如下: "Microsoft Windows XP Professional" /fastdetect /NoExecute=OptIn 
5. 点击“编辑” 按钮打开boot.ini 文件，将其中的“”/NoExecute=OptIn”改为“/NoExecute=AlwaysOff”。 
6 保存文件，重新启动计算机。
7. 安装完ArcGIS以后，将 boot.ini 文件设置改回来，以重新激活数据执行保护的安全选项。
