GoToMyPC Command Line Install Options

I operate and install GoToMyPC weekly on machines in our environment.
Since v3601's release I am no longer able to install and register via Command Line
For example, this used to install and register GoToMyPC with the specified account: "gosetup.exe $GTMUser@Email.com $GTMPassword $GTMAccessCode -s -a -s"

Have the command switches been disabled or removed from the latest installer?
