JET引擎仅适用于32位应用程序，从不适用于64位。

您可能已经安装了64位版本的Access 2016，并且根本不能与JET一起使用。



说真的，我强烈推荐你废弃JET并转移到支持32位和64位引擎和代码的ACE。

The JET engine was only available for 32 bit apps, never for 64 bit.
The chances are that you have installed the 64 bit version of Access 2016, and that can't be used with JET at all.

Seriously, I'd strongly recommend you scrap JET and move to ACE which supports both 32 and 64 bit engines and code.
