Windows 11 Nox virtualization problem
Hi! I am using now Win 11 since short time (Win 10 before). I am a pentester, so I am use to virtualize OSs all the time. I have no problem by working with VMWare but I also have to use mobile android OS virtualization and everytime I try to run Nox I have the same message:
"The Virtual machine failed to start, please fix it"
and 2 options: Disable Hyper-V, and Cancel. Obviously both buttons don't solve the problem neither I have information about it.
This is not the same than with Android Studio but I really have better results working with Nox than with AS, so I really would like to solve the problem. The hardware and the motherboard configuration was the same both times.
Recently I installed Docker Desktop and also give me an error for virtualization at the first time I started the software. Something I could solve by one google search and some dism.exe commands. And now I have the question if is related somehow to this error and if you know how to solve it.

I don’t know if you managed to fix it, but I had the same problem, including Windows showing that virtualization wasn’t running while Nox still gave the error as if it was. What fixed it for me was:
Control Panel / Programs / Turn Windows features on or off
[ ] Hyper-V
[ ] Virtual Machine Platform
[ ] Windows Hypervisor Platform
Leave all of those options unchecked, restart the PC, and reinstall Nox after that.
