I download the free 2017 Corporate Business Tax software but it is now asking for a license key. How to I activate it? Thanks

 2017 is permanently closed on Intuit.  You would need to find a license and buy the product. Sometimes old TurboTax software will be offered on eBay or Amazon.   You can also do a Google search for the product.  Does the site where you downloaded also sell the license?  TurboTax Business is never a free product.
