We solved it: You can Install BAT Files over the Dell Wyse Management Suite (Apps) Important info about the BAT files: You have to insert "EXIT" at the end otherwise there is a loop example: [NAME] off "Command to do" EXIT   Best Regards Donwurzel
Dear Community  We try to Upgrade the Teamviewer Version 9 to 13. In this process first you need to install the Teamviewer 13 on the ThinClient, that's no problem.  After that you have to run a Teamviewer_Assignment.exe Tool to import all the new clients to your Companys Account. How can you manage to run for example the Teamviewer_Assignment.exe with some special Parameters on all Clients with Admin Rights, because all of the Clients have to come in the Teamviewers Company Account to make Rules for the Client over the Teamviewer Management Site. The Thin Clients are not joined to Domain thats why GPO doesent work. thx for your Help best Regards Donwurzel
