interesting: When the AppStacks are connected i can copy and replace the files. After that i can use it and open Word whitout any delete of the startup folder files.
Here is the workaround from the support:
I need to add the following key to the user:
reg add HKCU\Software\Microsoft\Office\Common\ClientTelemetry /v DisableTelemetry /t REG_DWORD /d 0xffffffff /f
After that its working fine
