I am not able to start any of the Mobile Emulators for Windows Phone 10 (version 10.0.10240).
When I start it from the VS 2015, it gets stuck at "OS is starting". In the Hyper-V Manager, I can see the status "Starting (10%)" for the whole time. After some time, the machine is automatically restarted and it gets stuck at "Starting (10%)" again. Then it timeouts again and the emulator shows an error: "The virtual machine cannot be started because the file rdvgm.exe that is required to start the RemoteFX Manager process does not exist". That is weird, because I do have the rdvgm.exe in the C:\Windows\System32.
I have seen that there are some questions with the same error, but they are resolved by fixing the network switch or by killing devenv.exe after it shows "OS is starting". I have tried both, but it did not help. The network switch issue is different (I have seen it on a different computer - in that case the emulator starts correctly, but VS is not able to connect to it). I am stuck at "Starting (10%)".
What can I try to get it working? Windows Phone 8 emulator is working without any issue.
Thanks
The problem was that Hyper-V detected a graphic card which is able to work with RemoteFX (integrated Intel GPU) but the dedicated one (AMD Radeon) was not supported. I was not able to convince Hyper-V to ignore the dedicated one. When I disabled the RemoteFX support for Hyper-V (unchecked it in the Intel GPU setting in the Hyper-V configuration), it started working.
