 * Hey [@luisgasser](https://wordpress.org/support/users/luisgasser/),
 * I assume you are trying to run the installer?
 * That can pop up for large packages > 2.1GB on PHP 32 bit or when the archive 
   has become corrupted. Is the archive over 2.1GB by chance?
 * Also, you might try to re-download in the event it became corrupted in transit.
   If the downloaded by FTP that can happen when in ASCII mode.
 * Let me know if that helps~
