Kenshin9977 0 Report post Posted February 16, 2020 Hi, I have an Epson XP-452 printer and followed the instructions available on this page in order to downgrade the firmware. So I did put it in special firmware update mode and connected it with a USB cable type B to my PC. The issue is that when I download the chipless firmware available on this page and run it on my PC. The issue is that when I run the EPFWUPD.exe I get an error about a "side-by-side configuration". I tried : Reinstalling every C++ redistribuable package Running sfc /scannow Running DISM.exe /Online /Cleanup-image /Restorehealth 2 other systems also under Windows 10 but version 1909 (against 1809 on my machine) Run sxstrace.exe but th output file is unreadable Am I doing something wrong ? Tbh I don't know what to try now so I'm open to suggestion Share this post Link to post Share on other sites
