Problem: ‘NTLDR.exe is missing’ error message at computer start-up.
Remove driver disk from floppy disk drive and hit any key to continue start-up

Problem: ‘Cross-distance too close’ or ‘Invalid calibration points, default value used’ error message when calibrating.
Solution: This problem can occur for four reasons:

Finger bounced or rolled when touching a location, causing a double-trigger.

Touching a location other than the targets.  In Pre-X version calibration, touching other than the three crosshair locations, such as the ‘set default’ or ‘cancel’ buttons.  In X version, touching anywhere other than the circles.

(Applicable to laptop add-ons and built-in touch screen kits only) Black slide connector and the cable are connected backwards.  Make sure both white dots are on the same side.

Internal hardware problem in either touchscreen or controller.  Contact tech support for more troubleshooting.

Cannot see first crosshair.  (applicable only in Pre-X* version calibration) or, only see two crosshairs, located at the middle of the screen and the upper-right corner.
The first crosshair is located in the lower-left corner of the screen.  Sometimes this crosshair can be obscured by the Windows taskbar remaining in the ‘up’ position.  Make sure your taskbar is set either to ‘autohide’ mode or is dragged down to minimal height when performing the calibration test.

Problem: Windows does not detect the touchscreen as new hardware on start-up.
There are two common reasons for this to occur.  Either the controller is not receiving power (due to a port problem or bad controller), or Windows already detected the touchscreen previously.

1. The first thing to check is whether the controller box is receiving power from the computer.  For USB controllers this is easy, if the red light is on, then it is receiving power.  For the ProE controller, you will need to restart the computer and watch the status of the light throughout the start-up process.  If it comes on and blinks at any point, then it is receiving power.  If the controller is receiving power, but not detecting, move on to read point 2 below.  If it is not receiving power, check the ports to make sure they are working.  If they are, then call tech support to report that your controller is not powering up.

2.  More likely is the chance that Windows already previously detected the touchscreen as new hardware and it was just incorrectly installed.  To check this, look in your Device Manager.  (In most Windows versions, right-click on ‘My Computer’ icon on desktop and select ‘Properties’)  Look for a listing called either ‘ET1032’ (ProE controller) or ‘ET1055’ (USB controller) [USB might also appear as ‘USB Human Interface Device’ under ‘Human Interface Devices’ section].  If you find either listing, remove it.  In Windows 95, 98, ME, remove the listing by clicking on it once to highlight it then clicking the ‘Remove’ button.  In Windows 2000 and XP, remove the listing by right-clicking on the listing and selecting ‘Uninstall’.  Once you reboot, Windows should find the touchscreen as new hardware.

Problem: I do not have a floppy disk drive on my computer.
Our drivers can be downloaded for free from our website, go to the downloads page.  If unable to download the drivers, Contact tech support and we will send you the drivers via email or find another suitable solution.

Problem: I’ve downloaded the driver from your website (or, had it emailed to me), what do I do with it now?
The driver file you have is zipped (compressed). As such, you will need a compression program to extract the files before you can attempt an installation.  Windows XP has a built-in compression program, skip to the section below for instructions on its use.  For other versions of Windows, the easiest solution is to download Winzip.  Winzip is a free utility, which can be downloaded from  After downloading Winzip, you will need to install it, then proceed to the next steps.

Standard steps to extract driver files using Winzip, include:

            -Double-click on zip file icon (this is the zip file you downloaded from our website)
            -Winzip will automatically open (if not, Winzip is not properly installed)
            -Click ‘I agree’ or ‘Use evaluation version’ to exit licensing agreement
            -Click ‘classic mode’ button to enter Classic mode (applicable if Winzip opens in Wizard mode)
            -Go to ‘Actions’ drop-down menu and choose ‘Select All’ (all file names will highlight)
            -Click ‘Extract’ and the extract window will open
            -In the ‘Folders/Drives’ sub-window, select where to save the files (disk or directory), click extract
            -Perform installation as described in the software installation manual

If using Windows XP, which has its own compression program installed

            -Driver zip file icon will look like a folder with a zipper
            -Double-click the folder w/ a zipper icon to see all the files in the zip
            -Go to ‘File’ drop-down menu and choose ‘Extract all files’
            -In Wizard, select where to save the files (disk or directory)
            -Perform installation as described in the software installation manual.
