Teamviewer host 14 auto account assignment and password

So I'm trying to setup a Teamviewer Host 14 installer to automatically assign to my account and into a group and automatically set the password (personal password for unattended access and password for options). These will be running on Windows 10 1803 computers. I created a new host MSI installer, downloaded the assignment tool, and made a bat file. After installing the MSI installer, I ran the bat file and nothing happened. I inserted my API token into the bat file.

TeamViewer_Assignment.exe -apitoken YOUR TOKEN -datafile "C:\Program Files (x86)\TeamViewer\AssignmentData.json"

 What am I doing wrong? And how do I get it to insert the password?
