    regarding the buildnumber it reflects the full version, the host version has another build number and not sure if there's an own changelog for that.

    You are incorrect. I just confirmed that the host and full version properties are both 12.1.13180.0. This is from the direct download under my account.

    After the product is installed the properties of the exe is as follows.TV_1.png

    In Windows 10 at least..

    Every time TeamViewer Loads, it updates the security of the AssignmentData.json so that only system administrators can read it....  the 'System' account has no access to this file, therefore TeamViewer_Assignment.exe cant read the file to do anything with it.

    Which means any GPO / batch file (BAT) cant do anything to Auto Assign it to our TV account. 

    You need to set a GPO to give your 'system' account full access to the file before it can do anything automatically.   Unfortunately every re-boot of the system TeamViewer re-sets those permissions........

    You just need to get the order and timings correct.......multiple GPO's zzzzz not enterprise ready.

    Basic Script for Bat file to fix teh security bug on Win10

    IF EXIST "C:\Program Files (x86)\TeamViewer\AssignmentData.json" (
    ping -n 45
    takeown /F "C:\Program Files (x86)\TeamViewer\AssignmentData.json" /D Y
    icacls "C:\Program Files (x86)\TeamViewer\AssignmentData.json" /grant SYSTEM:(F,WO)
    \\XXdddffff.local\gpo$\GPO_Installs\TeamViewer\TeamViewer_Assignment.exe -apitoken 123456-GDuHy&658zzzzz -datafile "C:\Program Files (x86)\TeamViewer\AssignmentData.json" -devicealias "${COMPUTERNAME}" -allowEasyAccess=true -wait=10 -verbose -proxyurl https://myproxyproxy:8080
    ) ELSE (
    echo filename. missing.

    Hope this helps someone...

    heads up, a new version of TV has been released.

    also the assignment tools is updated as well but not sure what has changed.
