Hello, I use Android Studio and I wanted to use the emulator. I installed HAXM and my error is : /dev/kvm is not found. I tried to install HAXM without Android Studio and I have two errors : - During the installation : Failed to configure driver : unknown error. Failed to open driver. And after Windows says : (I'm French, I translate) Windows has blocked the installation of an numerically unsigned driver . Uninstall the program or device who use use it and search a numerically signed version of the driver on the editor's website. I hope you can help me, thanks a lot.
