UTM Smart Installer: No devices with a CD-ROM partition were found!

Question

Hi, 
 i bought a new Sophos UTM Smart Installer through my distributor. When I try to "burn" the ISO Image i have downloaded as described in this KBA https://community.sophos.com/kb/en-us/121767 i am running into an error: "No devices with a CD-ROM partition were found!". To demonstrate the Problem i attached a gif record. 
 
 That's odd, since the CD-ROM partition is definetly there. Does anybody have an idea what the problem could be? 
 Version: UTM Smart Installer 2.2.0 
 Windows 10 Pro x64 
 Thanks in advance and greetings :)

Currently still under investigation. 
 As said, simply use a own Stick and reimage the Appliance with your own Stick will help to get a working stick.

In the meantime, simply use a own USB Stick and quickly reimage the appliance.

 I know, not the best solution but as a workaround, this works fine.
