Hello there, I am interested in buying a license key to make my WF-5620 chipless. Firmware upload is completed, I have fear I may have problems with your windows application and firewall. Do you offer support to make the License app work ? Thank you, resetters ! =========== Yes sure

It's really easy to use and has saved me tons of money over buying new printers. I've reset my current printers several times and have used them for over 5 years thanks to these reset keys.
