As I do not have product key for Office 2016, I could not reinstall Office 2016 with product key either.

I tried with my registered Microsoft Account, but that is also not showing Office 2016 in the list of programs. As the warranty of my laptop had expired by this time, Dell also did not help me, although I sent them a mail mentioning the service tag. Hence from end 2018, I could not use Office 2016 for which I paid to Microsoft through retailer. You can download and install Office 2016 for Mac as a one-time purchase, or if you have an Office 365 Home, Office 365 Personal or Office 365 University.

But I could not reinstall Office 2016 as I did not have Product key. I tried to format the Laptop on my own and could reinstall Windows 10. I had copied my Windows Product ID from Laptop. In December, 2018, the Laptop started malfunctioning. The retailer from whom I had purchased my Dell Inspiron 5559 Laptop in May 2017 neither gave me Windows Product ID and Product Key nor the Office 2016 Product ID and Product Key, although I had paid for these.
