MT 7 Software, a member of the MicroTouch(tm) Software Suite, provides
unified driver support for MicroTouch touch technologies over a wide
range of operating systems. This version, 7.12, adds support for
multiple monitors and touch screens on a system. This product includes
a driver, a control panel, a calibration tool, and a touch monitor
that provides enhanced touch features on your Windows 2000, XP, Server
2003, or Vista system.

* Multiple monitor and touch screen support is now available. The
  Multiple Monitor Manager tool allows the assignment of touch screens
  to different monitors.
* The control panel allows selection of a controller to configure.
  This allows configuring individual controllers when multiple
  controllers are present. If only one controller is present, that
  controller is automatically selected.
* The control panel allows assignment of a unique ID number to a
  controller. This enables the Multiple Monitor Manager to identify
  the correct controller during mapping. The Advanced Options tab in
  the control panel allows access to the unique ID number assignment.
* This release of MT 7 also provides a new edge adjustment tool. This
  tool defines a region of the touch screen that positions a touch
  closer to the edge to compensate for the inability to touch near a
* The installer is smaller to ease the downloading of MT 7. The
  process of recording a silent installation and replaying it has
  changed. Unlike the prior uninstaller, the new uninstaller just
  uninstalls the product; to upgrade the product, you need to rerun
  the Setup.exe file. The installer should also resolve all issues
  with conflicts with older drivers.
* Another enhancement is the controller reset button. This button in
  the control panel resets the firmware on a touch screen controller.
  This is mostly a diagnostic tool.
* MT 7 now supports Windows 2003 Server and Vista.

Hardware Prerequisites

* MT 7 runs on most computers that run Windows 2000, Windows XP,
  Windows Server 2003, or Windows Vista.
* One or more of the following MicroTouch touch screen controllers:
  - MicroTouch EX II serial or USB controllers
  - MicroTouch SC400, SC500, and SC800 serial or USB controllers
  - MicroTouch DST serial or USB controllers
* Depending on the touch screen, either a serial (COM) port or a USB
  port is required.

Software Prerequisites

* MT 7 requires Windows 2000, Windows XP, Windows Server 2003, or
  Windows Vista.

NOTE: If you have other touch screen software, such as MicroTouch's
      TouchWare software, you should uninstall it. Reboot the system
      after uninstalling the software.
* Using Windows Explorer, browse to the software distribution and
  double-click on the Setup program to start the installation. If you
  downloaded the distribution, unzip the file into another directory
* Follow the instructions given by the Setup program. There are
  normally three options: Full, Typical, and Custom. If a version of
  MT 7 Software for Windows is already installed, a fourth option,
  Upgrade, is also available. Full installs all options. Typical does
  not install the Calibration Tool or Multiple Monitor support. You
  may choose to Custom or Upgrade to customize your installation.
  These allow you to select which components to install.
* During installation, you will get messages about finding new
  hardware. This is the MT 7 software registering your touch

The first step in producing a silent installation is to record your
standard installation. Open a command line window and set your working
directory to the directory containing the MT 7 for Windows setup
program. Issue the command "setup -r" and run the installation

When the installation finishes, it creates a recording file,
setup.iss, in your Windows system directory (such as C:\Windows). Copy
this file to the directory containing the MT 7 for Windows setup

To run the silent installation, simply issue the command "setup -s".
This replays the installation you recorded above.

Note that the silent installation fails if the installer reacts
differently than when it was recorded. For example, if you record an
installation using the "Upgrade" option and replay it on a system
without MT 7 for Windows, the installation may fail. You should test
the silent installation on all expected configurations.

This version of the control panel introduces support for multiple
monitors and touch screen systems. At this time, this new feature does
not support "splitter" systems where two monitors appear as a single
monitor to the Windows operating system.

To see if your system uses video splitters, open the Windows Control
Panel and select the Display option. Go to the "Settings" tab. If the
number of monitors shown is different from the number of physical
monitors, then you have a splitter system.

This is only a problem if each of the monitors shows a different part
of the desktop. If each monitor shows the same part of the desktop,
the MT 7 for Windows software can support this.

The MT 7 for Windows software can support such systems with additional
manual configuration. Contact your Field Application Engineer or
Technical Support representative at 3M Touch Systems, Inc., for
additional information.

In some applications, it is desirable to hide the cursor. The MT 7 for
Windows software provides a blank cursor file so that you can hide the

During installation, select either the "Full" or "Custom" installation
option. If you select "Custom", go to the "Utilities and Tools"
section and select the "Blank Cursor" option. This puts a file,
BLANK.CUR, into the MT 7 for Windows directory.

Copy this file into your Windows "Cursors" directory. There should be
other files with the extension "cur" in this directory.

Open the Windows Control Panel and select the Mouse option. Select the
"Pointer" tab and click on the "Browse" button. Browse to the Windows
cursor directory if not already there and select the BLANK.CUR file.
Click on "OK" to set the hidden cursor.

Using the control panel, it is possible to change which button on a
mouse generates the "left" and "right" clicks. This feature allows
left-handed people to use their index finger to produce a left click.
This setting causes the touch screen driver to also reverse the
meaning of a touch. Normally, a touch produces a left click. With the
changed setting above, a touch starts producing a right-click.

To address this, edit the file "TwFactory.cfg" in the MT 7 for Windows
software directory. If this file is empty, add in the text:


Between these two lines, add a new line:


Save the file.

Open a command line window and set your working directory to the MT 7
for Windows directory. Issue the command:

   TwCfgUtil /u TwFactory.cfg

At this point, your touches start producing the desired left-clicks.

If your system supports multiple users, you may need to create
separate files, such as TwLeft.cfg and TwRight.cfg. In TwLeft.cfg, set
SwapMouseButtons to 1 and in TwRight.cfg, set SwapMouseButtons to 0.
Add the above TwCfgUtil to each user's Startup menu or login script,
using TwLeft or TwRight as appropriate.

Two programs, TwMonitor.exe and TwUI.exe, write data to the registry.
The new Windows Vista security interferes with this function. If you
use MT 7 with Vista and it seems that any changes you make through the
control panel do not work, you may need to configure this new security

The new Vista security is known as "User Account Control" or UAC.
There are many options available to make an application run under UAC.
One very insecure solution is to disable UAC for a user's account.
More secure options exist, including the use of the Application
Compatibility Tool. Since a system's security is specific to its
environment, consult with your IT department to determine the best
way to make the necessary adjustments.

* Installer
  - Issue 612: If the reply to the Microsoft dialog about installing
    an uncertified driver is "Cancel", the installer proceeds even
    though the driver is not installed.

* Calibration Tool
  - Issue 343: On a multiple touch screen system, when prompted to
    select a touch screen for calibration, if the "Cancel" button is
    pressed instead of selecting a touch screen, then the calibration
    tool inappropriately presents an error message.

* Miscellaneous
  - Issue 220: The right-click tool responds only to touches and not
    to the mouse.
  - Issue 843: The Windows' "swap mouse button" setting does not
    affect MT 7. See the above section "Left-Handed Mice" for details.
  - Issue 849: The control panel's "Version Information" tool does not
    show the version number of the drivers.
  - Issue 885: All users must be at the same security level to run the
    Control Panel.
  - Issue 893: Edge adjustments affect manual linearization. Before
    performing manual linearization, change the value of all edge
    adjustment sliders to the "0" setting. You can restore the sliders
    to their original settings after performing the manual

Version 7.12.0, February 1, 2007

* Multiple monitor and touch screen support now available
* New edge adjustment tool.
* New smaller installer
* Addition of controller reset button
* Support for Windows 2003 Server and Vista.
* Changed the EX II serial controller initialization to include a
  reset command.
* Changed TwService.exe to statically link against the MFC libraries.
* Restored an accidentally deleted feature so that EX II USB
  controllers are now reset when first connected with driver.
* Corrected spelling and grammar mistakes in the calibration library.
* Improved the text out of the calibration library to prevent
* Improved the calibration timeout for USB controllers.
* Calibration temporarily changes the touch mode to "draw" mode during
  calibration. Before, the "draw" test would not work properly.
* Corrected a problem where calibration screens appeared only on the
  first monitor instead of the one being calibrated.
* Added an "/I" command line switch to ignore the last dialog normally
  presented by the standalone calibration tool.
* Changed the label of the controller-specific tabs in the Control
  Panel to "Controller". This used to be the name of the controller
  family. This name is now available on the page itself.
* Reduced the amount of text explaining linearization and frequency
* Removed the tooltip (flyover) associated with the "Calibrate" button
  in the control panel.
* Removed the communication port field from the calibration tab of the
  control panel.
* Relabeled the "Controller Information" box to "Support Information"
  on the calibration tab of the control panel.
* Reorganized the old "Reset Software" and "Restore Controller" to be
  included in a box called "Restore Factory Settings". The individual
  buttons are now called "Software" and "Controller".
* Calibration now allows the calibration of a touch screen in a
  multiple monitor situation and there is no corresponding entry for
  it in the configuration database. In such cases, the touch screen is
  assumed to be mapped to the first display.
* Issue 52: The Setup program now displays an hourglass when it is
* Issue 162: The setup tool now responds to the Cancel button once it
  starts to copy files.
* Issue 182: The uninstall tool now terminates if any MT 7 program is
* Issue 221: The setup and uninstall tools no longer create any DOS
* Issue 253: The uninstaller does not remove any user data files. This
  is done by design.
* Issue 274: The uninstaller now removes any configuration data in the
  registry. Some Windows related entries may remain.
* Issue 342: A silent installation now detects the presence of an old
  copy of TouchWare and terminates if it finds TouchWare.
* Issues 592, 812: There are three touch targets presented during
  calibration. For SC controllers, the third target is for the
  controller's three-point calibration. For other controllers, the
  third target is a software target that does not affect the
  controller's calibration. Before, the calibration terminated with a
  liftoff for SC controllers and a touchdown for other controllers.
  Now, the software waits for a liftoff for all controllers.
* Issue 814: The control panel's "Version Information" tool now shows
  the version number of the TwService.exe program.
* Issue 850, 859: The Touch Monitor program is no longer an option and
  is now always installed.
* Addressed an installer error which disabled calibration if only EX II
  serial support was requested. This was observed on early copies of
  MT 7.12.
* Addressed a calibration problem observed with serial controllers on
  newer, faster CPUs. This was observed on early copies of MT 7.12.
* Addressed an issue where the Control Panel reported the wrong
  frequency for capacitive EX II controllers if the frequency used was
  not one normally supplied by the Control Panel.
* Changed the display of the EX II controller frequency so that it is
  now in whole numbers.
* Addressed an issue where the Multiple Monitor Manager would crash the
  first time it was run on some systems. This was observed on early
  copies of MT 7.12.
* Addressed an issue in the installer which failed to properly create a
  custom installation path during a silent installation. This was
  observed on early copies of MT 7.12.
* A new message now appears when a touch screen controller's frequency
  is changed informing the user not to touch the touch screen.
