Windows Server 2012 not supported?

[dreiohrhase]

Hi folks,

I just discovered NextPVR (being frustrated using the Plex DVR solution).
I tried installing it on my Win7 laptop and everything worked well (just for testing purposes).
I could scan for channels and get EPG, record shows from different tuner hardware.

Then, I went for installation on Win2012 Server (64-bit) and while it installed without error, trying to scan channels for any SAT-IP tuner I own (AVM Fritz!box 6490 cable, AVM Fritz!W-LAN repeater DVB-C ).

After installation, going to Settings - Devices shows noth my tuner hardware devices (each with two instances). Clicking on any of them (on W2k12) then configure for Kabel Deutschland and scan for channels.thtows an error "Unable to start device".
I simply cannot access any of the devices.
I have all firewalls disabled, I can access the https localhost release note URL mentioned in another thread.

And I cannot stop or re-start the PVR recording service.

The following error shows:

Unable to stop service: System.InvalidOperationException: Der Dienst NPVR Recording Service auf dem Computer . kann nicht beendet werden ---> System.ComponentModel.Win32Exception: Der Dienst kann zurzeit keine Steuerungsmeldungen annehmen
--- Ende der internen Ausnahmestapelüberwachung ---
bei System.ServiceProcess.ServiceController.Stop()
bei NCtrl.Program.Mai(String[] args)



This is the part of the logs that look interesting to me...

I would happily replace my Plex DVR with your software, but W2k12R2 is the only computer where I could run it off.
Can you help me, please?
