Unable to connect to Access database

Hi a_rp ,

According to your description, there are four solutions that can be tried for such problems:

1. Change the version of Power BI Desktop to match the bit-version of your Microsoft Office installation.
2. Change the bit-version of Microsoft Office to match the bit-version of your Power BI Desktop installation:
3. If the error occurs when you attempt to open an .XLS file (an Excel 97-2003 workbook), you can avoid using the Access Database Engine by opening the .XLS file in Excel, and saving it as an XLSX file.
4. If the previous three solutions are not feasible, it's possible to install both versions of the Access Database Engine.

For more details, you can read related document as below:

If the problem is still not resolved, please provide detailed error information and let me know immediately. Looking forward to your reply.

Best Regards,
Henry
