Error while adding data

[SubhashniTaylor]

I am working with ArcGIS Version 10.8.2. I get the following error message when adding excel spreadsheets to ArcMap:

Failed to connect to database. An underlying database error occurred. Class not registered.

I'd be grateful for any advice on how to resolve this issue.

Have you installed the Microsoft Access Database Engine 2016 Redistributable driver as per this support page (right below the add data picture)?

Thank you for this suggestion. I have tried this but am still getting the same error message.

Any solutions to this problem? Same here... cannot add excel spreadsheets.

Microsoft Access database engine 2016 is installed.

EDIT: Seems like, you cannot open/view any spreadsheets in ArcCatalog before adding them to ArcMap. You need to use the catalog pane to add the tables to prevent any (misleading) error messages.
