I have installed all the recommended runtimes on related Answers marked as Accepted/working:我已经在标记为已接受/工作的相关答案上安装了所有推荐的运行时：

Microsoft Access database engine 2010 (x64) Microsoft Access 数据库引擎 2010 (x64)
Microsoft Access database engine 2016 (x64) Microsoft Access 数据库引擎 2016 (x64)
Microsoft Access Runtime 2010 (x64)微软访问运行时 2010 (x64)

but still the same issue.但仍然是同样的问题。

Setting the x86/x64 platform in Windows Forms project did not help.在 Windows 窗体项目中设置 x86/x64 平台没有帮助。

Setup:设置：

Microsoft Windows 10 64-bit Version 1809 build 17763.437 Microsoft Windows 10 64 位版本 1809 内部版本 17763.437
Microsoft Visual Studio 2015 14.0.25431.01 Update 3微软 Visual Studio 2015 14.0.25431.01 更新 3

There really is strange mixture of platforms.确实存在奇怪的平台组合。 I have installed all the necessary available within 64 bit and the connection resulted in "The Microsoft.ACE.OLEDB.12.0 provider is not registered on the local machine".我已经在 64 位中安装了所有必要的可用程序，连接导致“Microsoft.ACE.OLEDB.12.0 提供程序未在本地计算机上注册”。

When I tried to install the 86 bit version, I got the " You cannot install the 32-bit version of Microsoft Access Database Engine because you currently have 64-bit Office products installed... ": Setup Runtime error当我尝试安装 86 位版本时，出现“您无法安装 32 位版本的 Microsoft Access 数据库引擎，因为您当前安装了 64 位 Office 产品... ”：安装运行时错误

I followed the Merav Kochavi's advice to run the also the 32 bit version setup using /passive parameter (" AccessDatabaseEngine.exe /passive ") and it went without the error message and now IT WORKS!我听从了Merav Kochavi 的建议，使用 /passive 参数（“ AccessDatabaseEngine.exe /passive ”）也运行了 32 位版本设置，并且没有出现错误消息，现在可以正常工作了！ Test connection succeeded.测试连接成功。

Thank you all for help!谢谢大家的帮助！

If it helps anyone else, I was having the same issue.如果它对其他人有帮助，我也遇到了同样的问题。 One Project would work, but not the other.一个项目可行，但另一个不行。 I went to Add/Remove Programs, Uninstalled Microsoft Access database engine 2010. Then I reinstalled it with the MSI (NOT the 64 bit one).我去了添加/删除程序，卸载了 Microsoft Access 数据库引擎 2010。然后我用 MSI（不是 64 位的）重新安装它。 Here is the link to MSI: https://www.microsoft.com/en-us/download/details.aspx?id=13255这是 MSI 的链接： https ://www.microsoft.com/en-us/download/details.aspx?id=13255

Lastly, in VS, still make sure that you click Project, Properties and check the box for Prefer 32-bit.最后，在 VS 中，仍然确保单击“项目”、“属性”并选中“首选 32 位”复选框。 Cheers!干杯!

As long as you check the Prefer 32-bit option, this problem is overcome if you have run the Microsoft Access database engine 20xx.exe file to register the engine.只要勾选Prefer 32-bit选项，运行Microsoft Access database engine 20xx.exe文件注册引擎就可以解决这个问题。
