Assignment.json never created

This is my process as we deploy TeamViewer at this location, it has worked on all machine except three (out of 72).  Sometimes it takes a bit of time for AssignmentData.json to show up but it does.

 here is my process

 I run TeamViewer_Host-xxxxxxxxx.msi

Wait for AssignmentData.json to show up in ${ProgramFiles}\TeamViewer\

Run teamviewer.bat

On three machines AssignmentData.json never gets created therefore the bat file fail with file not found.

 The bat file contains only:

 TeamViewer_Assignment.exe -apitoken xxxxxxxxxxxxxxxxxxxxx -datafile "${ProgramFiles}\TeamViewer\AssignmentData.json"

Pause

its worked 69 times but will not create the file on these few machines.  I have looked thru all the logs and see nothing that tells me why. 

 I have cleared the registry of all teamviwer entries as well as this will cause the file not to be created.

I am at a loss as what to try next.
