No Urbackup after installing Appliance

Hi, we plan to switch over from urbackup ( community ) to the appliance but we stuck.

We have a PowerEdge R730xd Server where we was running the UrBackup ( Community Edition ) on Windows Server.
No we have installed the Appliance ( Bare Metal Version ) on a internal USB Stick ( 32 GB ).
When we restart the Server after installing the Appliance, we see with a IP Scan the Server IPMI and also the Esxi interface, but what we dont see is the UrBackup installation.
Bevor someone ask, yes i have tryed also HTTP
We can access the Web Gui for the HyperVisor but without username and password we cant login.
Have anyone a tipp for me ?

P.S. I wounder if there is a installer for the Appliance on windows aviable ?

Regards
Christian
