The electronic translation is: "the Nvidia control panel could not be installed, which may affect driver functionality. The most recent driver that worked will now be restored." After restarting, all the drivers for the video card disappear, and I have to reinstall them.
Help me if you can!

I found many negative reviews about driver 195.62 on forums. So, I'd better continue using 191.07. Or even 181.20, because 191.07 disables the Nvidia control panel.
