Hi nmicallef,
Welcome to the Community Forum! It's great to have you join us!
Have you attempted restarting Excel to see if it resolves the issue with the error message, "This add-in could not be started"? A quick restart can often refresh the program, enabling the add-in to initiate correctly. If restarting doesn't resolve the issue, it may be beneficial to check for any updates to both the MYOB add-in and Excel itself. Sometimes, updates address compatibility concerns that may be causing the problem.
Additionally, the Help article, Getting Started with MYOB for Excel, may offer guidance on optimizing Excel for seamless integration with MYOB.
Feel free to post anytime you need further assistance.
