Questions:

I have .xlsx file with 27,000 rows. When executing the SSIS package on the server I get the above error. I have tried running the package in 32-bit mode, it did not work. Microsoft does not have a good explanation. I have installed access driver on my machine and on the server.

How to&Answers:

Assuming that you tried running in 32-bit, and you downloaded Access Database Engine and the issue is not solved

This is caused by a windows security update, this is noticed in the Microsoft Support article, also they provided patches link.
