Epicor 10 installation

Hello,
I tried to install Epicor 10.2.700.28. I got System.UnauthorizedException: server is not available.
just wonder if I need use “manager” for the admin console or I can use any account for the admin console. for the Net.Tcp endingpoint binding: I use UsernameWindowsChannel.
don’t know where I missed.

any suggestion appreciate.

Regards,

Eddy
