I am having a similar problem with an Epson WF-3730.  Attached is the screenshot from the WIC tool.  License tool does reports printer as unsupported.

The above license file fixed my issue completely.  I am now able to use my Epson WF-3730 with an ink cartridge that was originally not accepted by the printer (a brand new 3rd party one that had a chip that was incompatible with the printer). 

The activation procedure was exactly as described (easy) with this new license file application!

Great customer service and a fantastic solution to using 3rd party inks with the Epson WF-3730!
