[?-]: .fwx file to .hmi file - Siemens wincc flex

[codientt]

Hi all!
You help me transfer *.FWX file to *.HMI file in the WinCC flex. Right now I only have *.FWX file, I need to change the system, but I do not know how to switch the .HMI wincc flex.
My client want some changes in system and I don`t have project .hmi file because I lost him. I have only .fwx file which is used like runtime aplication for production. Can I use this .fwx file for doing changes for client and how??
Thank you very much
