I have an 18.5 inch wide Panelmate touch screen installed on a fiber laser machine. touch is not working properly and it can't be calibrated. When I try to open calibration interface, it gives an error message that some files are missing. I tried to uninstall touch software and reinstall it again, but it gives me a message that another version is installed even though I uninstalled it. I tried to install some other touch software but it didn't work. anybody knows how to fix this problem or can give me some guidance?
