Share complete details, hwid, what you did, and what seems to be wrong, there are a ton of different devices, problems and solutions
99.9% of the issues people have with the drivers “not working” is their install missing basic system/chipset drivers which need to be installed via SDIO or similar.
Never faced ever a trackpad issue, but I have a ~50Gb offline driverback just in case 
I did all the the thing step by step which mentioned on your website to Install windows and everything worked properly after that i made windows installer usb and install windows on my acer chromebook plus 514 after the setup i install all the drive provided on your website for my device step by step but stll facing trackpad not working headphone jack not working bluetooth not showing
there is nothing on my website about installing Windows, other than don’t ask me for support in doing so. I just provide the firmware.
If you’re not Windows savvy enough to know how to look at Device Manager for missing drivers, use a tool like SDIO, etc. then installing Windows on a Chromebook is not for you. Installing the drivers provided by coolstar is not sufficient.
