    @mamertz , Such error occurs usually when output folder is missing or any of the file used in the app does not have copy permission.

    @mamertz en mi caso es que en la carpeta seleccionada en Directory of local Website habian archivos temporales, (tmp) los borre y listo... Tales archivos se crean al abrir archivos (*.*) con programas.... espero ayudarte y a los que vengan despues.
