the message means the user account your are logged with doesn't have required permission to create folders.
I googled for 1008:9,-5000 and found out these links:
Installation FM14 serveur : erreur 1008:9,-5000 accès non autorisé beginning is in French, but then in English.
Other links, not related to FileMaker, states the same, about missing permissions.
It seems that you cannot be running El Capitan(10.11) when using FMS 14.0.1.x installer. I simply re-installed Yosemite(10.10) and everything worked flawlessly.
