What username and password do I enter when installing Flash Player on Mac?

[Guest]

I've created a new account and password for Adobe Flash Player. When I come to install it, it comes up with my old username and won't accept the password and throws me out.

What is being asked for is the Machine, the OS Username, password. The one you use when you start your system.

That is an install prompt by the Operating system to allow changes to be made to your drive and OS.
