hi

I get the following error when I try to install magento on my local computer (win10).

Note that this error comes in the beginning, when I access C:\xampp\htdocs\folder folder

Warning: require(C:\xampp\htdocs\folder\vendor/magento/module-media-storage/registration.php): failed to open stream: No such file or directory in C:\xampp\htdocs\folder\vendor\composer\autoload_real.php on line 71

Fatal error: require(): Failed opening required 'C:\xampp\htdocs\folder\vendor/magento/module-media-storage/registration.php' (include_path='C:\xampp\htdocs\folder\vendor/magento/zendframework1/library;C:\xampp\htdocs\folder\vendor/phpunit/php-file-iterator;C:\xampp\htdocs\folder\vendor/phpunit/phpunit;C:\xampp\htdocs\folder\vendor/symfony/yaml;.;C:\xampp\php\PEAR') in C:\xampp\htdocs\folder\vendor\composer\autoload_real.php on line 71

any ideas?
