推荐答案

从这一点开始我们就不能准确了，但是既然你提到了一个MDB文件，你应该从检查开始做一些事情：

1）安装应用程序时是否安装了MDB文件？

2）您是否将文件安装在应用程序新实例可访问的位置？ />
3）您是否告诉应用程序文件的确切位置？

4）文件是否在合理的位置？该应用程序是否有权修改文件夹内容？

5）您是否尝试使用多个用户访问同一文件？如果是这样，那么期待一个痛苦的世界......

We can't be precise from that little, but the since you mention an MDB file there are a couple of things you should start by checking:
1) Did you install the MDB file when you installed the app?
2) Did you install the file in a location accessible to the new instance of the application?
3) Did you tell the application exactly where the file was?
4) Is the file in a sensible place? Does the App have permission to modify the folder contents?
5) Are you trying to access the same file with more than one user? If so, then expect a world of pain...

一旦检查数据库连接字符串。

once check database connection string.
