installed fopnu to give it a try, installed ok but when i tried to launch it got a error message your computer has a problem and we will have to restart now, computer restarted and fopnu had been uninstalled automatically, running windows ten with creator update

it sounds like your computer crashed before it had time to save the fact that it installed fopnu. try to install it again.

you did download it from here right? https://www.fopnu.com/download/

I had the exact same issue happen with Tixati (twice)- where it was automatically uninstalled and this week after running fopnu for nearly 6 months it was uninstalled upon a reboot automatically with no warning.

Fortunately when you re-install, the configurations are restored and not reset.
