What is failed to start emulator error?
After installing Gameloop for the first time and Downloading Pubg or COD Mobile you might face this error which pops up and says Failed to start emulator after you run Pubg and now a days it happens even on Call of Duty on Tencents new Emulator named GameLoop.
Actually during installation of the game it runs once and is saved in the memory. If you will restart your laptop or desktop it still will show as it is working. So you will have to terminate the process that is keeping it alive.
How to Fix?
First Close your Emulator completely and Download Process Hacker from Link Below.
After Downloading Install and Run the program.
In the search of the program just write Aow and you will be able to see aow_exe.exe process.
Right click over this process and terminate. If terminate option is not active make sure you restart your program as ADMINISTRATOR.
