[robyroby]

ciao, were days that I worked with a visual style, and today when I turned on the computer and I wanted to change the theme that i had with this new theme, appe ared Windows Classic. I just can't understand where is the problem, was fine.
What could I do now?
thanks

Try installing your theme with this https://www.door2windows.com/windows-...sta-with-ease/

Unfortunately files can get overwritten by Windows and the minute anything suspect comes up it will ditch themes and replace it with the default 'panic' theme. Themes installed with this utility seem to be more durable.

This did not work. I have extracted all the images and I rebuilt everything.
Now is fine.
thanks

Sometimes when there is an error or something wrong with that file it goes to classic style.
