Hi every one. This solution applies for all the zx-4250 or higher models since have the same touch panel
I purchased an used Gateway zx-4931-31e running windows 7.
Since it is touchscreen i tough it would run nice on windows 8 for its touchscreen display.
So i installed windows 8.1, tested the touchscreen. Nothing Happened, wasn't responsive so i checked the drivers and everything seemed ok.
Then i found a lot of people with the same issue after upgrading to windows 8. Spent hours and hours looking for the right driver and nothing.....
Well kept looking for more hours and hours and finally found out a compatible driver.
So here is for you people.

-----This link shows zx-4931 computer drivers, the touch driver is the same for all zx models 4250 or higher--- On the setup will say ACER. Acer and gateway are the same BTW
Choose your version of windows 8 and download ideacom touch driver
open the folder and run the setup, restart your pc and DONE!
