Unable to open TAB files linking Access or Excel files in MapInfo Pro 64-bit


In 64-bit MapInfo Pro, I receive an error or crash when trying to open TAB files that linked to an Access or Excel file. Or MapInfo is simply crashing when trying to open a workspace.

Note that if you save the XSLX file in Excel as a CSV or legacy 97-03 XLS format, these still open.


This is due to Microsoft not supporting side-by-side installation of Office 32bit and 64bit versions. 
There is a workaround that has been tested with Office 2013 or Office 2016 (365) installed. If you are using Office 2010, it is recommended you upgrade to a newer supported version of Office first.

In the start menu search for "Access Database Fix". Run this shortcut and click OK on the prompt to apply.

In Discover version older than 2017 Update versions, please download the file attached.

Then extract the files, and simply double click to run the AccessDatabaseEngineUtil.exe. Click OK on the prompt to apply.

If the issues persists, please do the following -

1. Manually uninstall all versions of the Microsoft Office Access Database Engine 2010 from the control panel.
2. Then run the AccessDatabaseEngineUtil.exe from the above download link.

If this still persists, try following the MapInfo solution here -

If these still do not resolve the issue, a more robust solution is to switch from Office 32-bit to a 64-bit version. There is a step by step for this here.

Note that this fix is not permanent, and may break when Windows Update automatically updates your Office installation. If this occurs, the fix will need to be run again.
