This is the error given and I've been given a bunch of 25 digit keys that the IT Company Purchased. They tell me they have tried to input them and they won't install. The Install licenses wizard has 7 Fields to Enter Groups of info.
My keys are in 5 Groups. Example: AB123 CD123 EF123 GH123 IJ456
Server1 is Windows 2012, Server 2 that I'm wanting to install these licenses to is Server 2016.
