3M™ MicroTouch™ Software MT 7 User Guide 59
3M Touch Systems, Inc. Proprietary Information – 25695M
A Previous Version of TouchWare Software Was Detected
Note: Before making any changes to the registry files, be sure to make a backup copy.
If the MT 7 installer reports this, then uninstall TouchWare by going to Start →
Programs → TouchWare → Uninstall TouchWare. Do not install MT 7 over a previous
version of software.
If this does not work (MT 7 still won’t install) then the Registry needs editing. Start
REGEDIT and browse to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MTSTCH and
delete the MTSTCH key.
