I have changed the reboot type of the firmware update to "3" and the installation works as expected.
But how could i suppress the upcoming cmd window?

I changed this line in the xml
<Package name="FWU_TBT_N1WTH" id="n1wth07w" version="17.0.0.3-N1**bleep**13W" hide="True">
But HideWindow still "False"

Could i set this property in the XML file?
The errorcode is happening, cause i stopped the firmware before it starts.
Thanks!
