The download site for Office to reinstall using your key is here-- products.office.com/.../download-back-up-restore-microsoft-office-products
I have had a dell 2710 AIO desktop for over 2 years, now out of warranty. I recently had issues and had to re-install windows. I now no longer have my office suite that I had purchased with the computer. Microsoft site asks you purchase it before download, but I want to download the software or app and then just use my activation key.  How do I do this?
