Unable to open HAXM device: ERROR_FILE_NOT_FOUND I am getting intel haxm error while running emulator. It was working 1 month back but stopped a while back. I tried a temporary solution to disable driver reinforcement which starts the emulator but it doesn't work in big app projects and whole app/emulator starts crashing. I have to disable driver reinforcement with each reboot to make it work. Not GOOD idea :/

Secondly, few guys said to enable vt in bios and I did that too but again same issue. Any suggestions?

Error and PC Info is listed below
Had the same problem in windows 10, which was solved by disabling Hyper-v and reinstalling HAXM via SDK Manager>SDK Tools>Intel x86 Emulator Accelerator
