EWF - No unattended access possible

Options

after activating the Enhanced write filter (EWF) on our embedded Win7, Teamviewer unattended access is no longer possible after reboot.

If the following exclusions are set, a connection is possible for a short time, but it breaks off after about 5 seconds of active connection each time, and a further connection is no longer possible.


fbwfmgr.exe /addexlusion C: \Program Files (x86)\TeamViewer

fbwfmgr.exe /addexlusion C: \Users\Administrator\AppData



If the EWF is deactivated, a connection is then possible again without any problems.


Do any other exceptions need to be defined? 


We are using Teamviewer 14.
