HP Envy x360 15t Touchscreen 2-in-1 laptop

HP Envy x360 15t Touchscreen
Microsoft Windows 10 (64-bit)

I have three questions regarding my HP Envy which I recieved in September, 2016.  1) how do I find the serial number? 2) how do I correct this system error? AccelerometerStexe - System Error. MFC120U.dll is missing. 3) I have an Espon Perfection V300 Photo Scanner, it works perfectly with Windows 7 on my work laptop. I cannot get the scanner with Windows 10 to work. I am connecting the scanner via a USB. The laptop recognizes the scanner and adds it as a device. However, it does not install any drivers to make the connetion between the scanner and the laptop.  I have tried multiple times to download the drivers from Epson.com and still does not work. The system is totally up to date and I know the USB works.  This is driving me crazy as I need this scanner to work with this laptop.
