Can't connect to MySQL server on 'localhost' (10061) after Installation

Question

I installed MySQL using mysql-installer-5.5.20.0.msi on Windows 7. From the cmd window, I run \"mysqlshow -u root -p\". It asked for a password, then return

Answer 1

I had this error - stupid mistake was, I was using -p3307 to specify port, whereas I should have used -P3307, i.e. capital P. Small 'p' is for password arg :)
