Calling from code fails

[AndreFabris]

\Artisan::call('backup:mysql-dump'); results in this error

exec(): Unable to fork [mysqldump -C -h "127.0.0.1" -P "3306" -u"root" --single-transaction --skip-lock-tables --quick "back_myadmin"]

While the plugin works on command prompt
php artisan backup:mysql-dump

Laravel 5.2, Xampp, Windows 10 local.

Any ideas? Thank you!

Not to worry about this, I used a different package which suits my needs better
