banvis 0 Report post Posted September 25, 2020 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. Share this post Link to post Share on other sites

banvis 0 Report post Posted September 28, 2020 I did everything exactly as instructed. After installing firmware checked firmware version using WIC utility and also in the printer menu, both confirmed that correct firmware is installed - CV14I9. When trying to activate I ran into the same outcome over and over again, as previously explained. Cannot get it through, despite firmware installed and having proper USB connection and shut down all mentioned processes before running Licence.exe Share this post Link to post Share on other sites
