This is the link to my new PCU 50.3-C hard disk ghost backup.
HMI is giving error during startup, and base software version and service Centre users menu is not showing up. Kindly try to run it in your system and diagnose what's wrong with it? So far i know is that files have been corrupted in E:/windows /system32/hmiman.exe etc
Kindly help me restoring my pcu50.3 to its original state so that i can run hmi properly and commission my CNC Lathe.
