Can't associate .ex4 file with current broker terminal (Windows)

 
I cant associate .ex4 file with terminal.exe of current broker. It always point to the previous deleted broker terminal. Tried everything , from deleted bak, ex4 files association in reg editor, cmd... still nothing. P;ease hep! Do not just advice apps default. 
 

Try resetting the platform settings:

    1. File menu->Open Data Folder
    2. Double click on "Config" to open the folder
    3. Close MT4 
    4. Delete the file "terminal.ini" (or rename it)
    5. Restart MT4
