Received 'Connectors can't be loaded:unable to open database file'

I am using version 4.2.0.4. I don’t have MS office installed in my local machine but when tried to apply some formula in excel or convert files it throws message saying ‘Connectors can’t be loaded:unable to open database file’

PS: Have libre office installed in the same machine

Not sure I understand the question. How can you apply formula in Excel if you don’t have it installed on your computer?

Can you post a screenshot of what you’re doing and the error you’re receiving?
