Installation Error

I have a problem in the installation progress.
On the last step I tried to deploy seafile with mysql on windows.

At this step of the instruction, I have the problem:

Create Database Tables for Seahub

Now we create the database tables for seahub.

Assume you have uncompressed seafile server to C:/SeafileProgram/seafile-pro-server-3.1.3,

Open a window command line prompt, and execute the following command:

mysql -u seafile -p seahub-db < C:/SeafileProgram/seafile-server-3.1.3/seahub/sql/mysql.sql

When I enter this in the commad line I get as an answer: No permission. (Zugriff verweigert)

How can I fix this??
