打开ArcMap能打开，Add Data 或打开mxd就出Runtime Error对话框。

对话框

Runtime Error!
Program: D:\Program Files\ArcGIS\Bin\ArcMap.exe
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application‘s support team for more information.

看看C:\Program Files\Common Files\Microsoft Shared\DAO下有没有这个文件，dao360.dll。

有就用regsvr32注册下，没有到百度下个拷过来，再注册。（方法源于网络）
