UPnP - Windows Vista

[evandro]

Hi,

i wrote the following code:

UPnPDeviceFinderClass finder = new UPnPDeviceFinderClass();
UPnPDevices devices = finder.FindByType("urn:schemas- upnp-org:device:Printer:1", 0);

it runs fine on XP, but, when i tried to run it on Vista, i got the error below.

Creating an instance of the COM component with CLSID {E2085F28-FEB7-404A-B8E7-E659BDEAAA02} from the IClassFactory failed due to the following error: 80070422.

Could anyone help, please?

Thanks.

I already tried to use impersonation and use "run as administrator", but i'm having the same error.

Ahh well are those UPnP objects aren't part of the .net framework, so you're getting them from some custom DLL. I would guess that the DLL does not exist or is not registered properlly on the vista machine?
You also may have to make sure the UPnP service is turned on on the vista machine to be able to use it?

Hi,

I started the service "SSDP Discovery", after i started the service "UPNP Device Host", then a run my application and everything is ok.
