You get this error when running your application:
Unable to update record. Operation must use an updateable query…
This error is generally caused when the folder containing your application’s Microsoft Access database does not have sufficient permissions to insert (write) records. This can occur when your database is in a separate folder from your application.
Add sufficient access permissions to the folder containing your Microsoft Access database necessary for records to be updated and inserted.
