Thank you for the quick answer.
I find the solution too.. When I just copy the child files manually to the child directory, I need reactivate the parent theme (stop it and activate it again).
But with any installing from child themes, the iconic pro service settings on the backend will be reset to default (lost the backround,- logo image, and color settings, etc.). Its recommended to export (backup) the options with the iconic settings service (when it works correctly, I never has try out).
