我制作了一个通过 ODBC 访问一些数据库的 VB.NET 程序。在 Windows 7 机器上它工作正常。在它安装的 Windows XP 机器上，但是当它打开应用程序时，会发生此错误。我在 Visual Studio 2012 上开发了这个，Windows 7 和 Windows XP 都是 x86，并且都具有我试图访问的相同系统 DSN。我到处寻找，但没有针对我的问题。有任何想法吗？提前致谢！

错误消息明确指出您的程序找不到 DSN。检查 DSN 的位数是否正确。请参阅http://support.microsoft.com/kb/942976了解一些 64 位/32 位混淆的描述。

遇到了同样的问题。在 Windows 7 64 位上有 1 个运行良好的 VB 项目。开始了另一个项目，复制了我需要的代码，但没有找到 DSN。阅读了弗兰克的评论后，我进入 VS 2010 中的配置管理器并添加了一个新的“任何 CPU”的“主动解决方案平台”，并重新运行了我的项目，一切正常。我的项目现在是 64 位，就像另一个有效的项目一样。

谢谢你的这篇文章，它解决了我的问题，虽然在我的例子中，我有一个在 SQLExpress 数据库上运行良好的 VB 项目，但是当我尝试将连接字符串更改为 Access 数据库时给了我上述错误。但在另一个项目中，我连接到一个 Access 数据库就好了。设置了“任何 CPU”，我将其更改为“x86”，然后它对我有用。
