Final Checklist for Success:

[ ] Downloaded driver from a verified forum or Archive.org.
[ ] Uninstalled old/broken drivers.
[ ] Disabled driver signature enforcement.
[ ] Installed using "Add legacy hardware" в†’ "Have Disk".
[ ] Confirmed COM port in Device Manager.
[ ] Tested with UPA software (read a known good chip).

If you still face issues, post your exact Windows version and the "Hardware Ids" from Device Manager (Details tab) to a forum like Badcaps.net for expert help. Support for over 500 memory chip models
