I tried multiple times to activate my chipless firmware after installed on my Epson Workforce Pro WF-C5790.
Attached is the screen shot of firmware installed , confirmed by using WIC utility, and error I get every time I ran the Licence.exe.
I shut down Windows Firewall and all security options, as well as Bitdefender Antivirus completely, and disabled Internet option for any proxy connections.
Still the same.
Please advise what is the problem, because if this doesn't work, I need to buy regular cartridges soon, which are costly, and I want to avoid that.
