问题描述

当我尝试使用MS Access数据库（.accdb）使用Crystal Report在VS 2008中创建报表时，我无法从提供程序列表中找到Provider ACE.12.0.OLEDB提供程序。但是只有Jet.4.0.OLEDB PRovider。这里有什么问题？

When I was trying to create a report in VS 2008 using Crystal Report using MS Access Database (.accdb) I cannot find the Provider ACE.12.0.OLEDB provider from the provider list. But There is only the Jet.4.0.OLEDB PRovider. What is the problem in here?

推荐答案

ACE DB提供程序在64位版本中不可用。如果您的应用程序（在这种情况下为Crystal报告）作为64位进程执行，那么它将无法引用ACE - 它仅为32位。请改用JET提供程序。

The ACE DB provider is not available in a 64 bit version. If your application (Crystal reports in this case) is executing as a 64 bit process then it will not be able to reference ACE - it is 32 bit only. Use the JET provider instead.
