Update unsuccessful C5290

Printer Activation Issue​

Problem Description​

Hello, this is my printer C5290 and it does not work with the license.exe. It says that the activation code writing has failed. I have followed the instructions of the Admin.

Activation Key​

Copy and paste Activation Key:

```

Additional Information​

Yes, dear, it worked previously. However, after updating to Epson's new update, I ran the Activation Key again, using a new key, but it failed. Thanks to the admin's help.

Troubleshooting Steps​

Firmware Check​

- Did you reupload chipless firmware back to the printer again after updating from Epson?
- What is the current version? You can check it in the printer settings or via WIC using the `report` button.
