1.3  Drivers Only Installation
  Windows 95, Windows 95 OSR2, and Windows NT 4.0 have the
  ability to load device drivers without running the Setup
  program. Loading the devices drivers this way, however, does
  not install the user interface programs such as the Logitech
  Enhanced Mouse Control Center. Using the "Have Disk" function

1.4  Work Around Installation for Windows 95
  If you experience difficulty running the installation program,
  under Windows 95, try launching the installer while running
  Windows 95 in Safe Mode. If this fails then install MouseWare
  To install MouseWare manually under Windows 95, restart your
  computer and press the F8 key when "starting Windows95"
  appears. Select Safe Mode Command prompt only from the
  Microsoft Startup menu. At the MS-DOS prompt type "A:" or "B:"
  depending on the drive you are using. Then type "T95 A:" or
  "T95 B:". This will expand all the compressed files. After
  running this you will need to load the drivers. See section 1.3
  for a description on how to do this.
1.5  Work Around Installation for Windows 3.1
  If you experience difficulty running the installation program,
  you may want to do a manual installation. Refer to section 1.2
  and proceed with the installation for DOS.
  Before rebooting you need to edit the SYSTEM.INI file located
  in the WINDOWS directory. Please change the following lines to
  read as follows:

1.6  Manually Decompressing Files
  Several files on the installation disk have been compressed.
  These files must be decompressed before you can use them. The
  SETUP program automatically decompresses these files during
  installation. However, should the need arise, we have provided
  a method for you to manually decompress these files. Compressed
  files have file names that end with a tilde sign (~). To
  decompress a file manually, use the LGEXPAND.EXE utility
  provided on the installation disk.
  For example, to decompress the file "WMOUSECC.EXE" to your hard
  disk, type:
  Please make sure that the destination directory (C:\MOUSE in
  this example) exists before you issue this command.
2.   Uninstall Program
  MouseWare can be removed from Windows 95 and NT 4.0 by clicking
  the Add/Remove Programs icon in the Windows 95 or NT 4.0
  Control Panel. Select Logitech MouseWare and press the Remove
  Windows 95
  The driver itself cannot be removed by this process. You can
  manually change the driver to another one as described in
  section 1.3.
3.   Features
3.1  Cloaking Feature for DOS and Windows 3.1
  The MouseWare DOS mouse driver works in conjunction with a
  special interface program called "Cloaking". The CLOAKING.EXE
  interface program allows the DOS mouse driver, MOUSE.EXE, to be
  loaded in extended memory, freeing valuable conventional and
  upper memory for DOS applications. CLOAKING.EXE is
  automatically installed during the standard MouseWare
  installation for Windows 3.1.
  Cloaking works in conjunction with a supported memory manager
  to enable the mouse driver to load in extended memory, using a
  mere 1k of conventional or upper memory.
  CLOAKING.EXE will work with any of the following extended
  memory managers:
   EMM386.EXE               Microsoft
   HIMEM.SYS                Microsoft
   RM386.EXE 3.03 or later  Helix
   QEMM386.SYS 7.1          Quarterdeck
   386MAX.SYS 5.0           Qualitas
  You will need to be running one of these programs in order to
  use CLOAKING.EXE. The EMM386.EXE and HIMEM.SYS programs are
  included with DOS versions 5.0 and above, and with Windows.
  Installing Cloaking:
  Under Windows 3.1, the installation program copies CLOAKING.EXE
  in the mouse directory and loads CLOAKING.EXE in your
  AUTOEXEC.BAT file. This will occur if your DOS version is 6.0
  or greater, you are running EMM386.EXE, and you are not already
  loading a version of CLOAKING.EXE.
  If you are running DOS only, you will need to do the changes
  manually. If you wish to install CLOAKING.EXE in the CONFIG.SYS
  file, add the line: "DEVICE=C:\MOUSE\CLOAKING.EXE" after the
  supported memory manager is loaded. If you wish to install
  cloaking in the AUTOEXEC.BAT file, add the line:
  "C:\MOUSE\CLOAKING.EXE" before the mouse driver is loaded.
3.2  Zooming in Windows 95 and NT 4.0
  In Windows 95 and Windows NT 4.0, some applications, as
  Office97, support the zooming. To zoom in such applications,
  just press the [Ctrl] key and roll your mouse's wheel (if any)
  or use the Universal Scroll button assignment. Be sure your
  application is Office 97 compliant and supports the zoom
4.   Troubleshooting
4.1  Detection Problems with PS/2 Pointing Devices
  If your mouse is connected to the mouse port and is not
  detected by the system, attempt the following step(s):
  1) Your mouse port might need to be enabled through the SETUP
     menu of your computer. Please check your computer
     documentation regarding the SETUP menu.
  2) If you have a mouse with both serial and mouse port
     adaptors, connect the mouse to the computer through the
     serial port. Reboot and check if the mouse is detected
  3) If adaptor(s) were not included in your package, your mouse
     was designed to work on only one type of port (Serial OR
     PS/2). Refer to your package for the type of port your mouse
  If the problem persists, please check for a possible computer
  BIOS ROM upgrade from your computer manufacturer.
  Some notebook systems, such as IBM Thinkpad, have both an
  external Mouse Port and an integrated Pointing Stick, which is
  connected to the Mouse Port. If your mouse is having difficulty
  running on the Mouse Port of this type of system, try using the
  serial port instead.
4.2  Serial Port Detection Problems with Serial Pointing Devices
under DOS and Windows 3.1
  If your mouse is connected to the serial port and is not
  detected by the system, add the following modification to the
  MOUSEDRV.INI file and reboot:
  or load the DOS driver with the following parameter
4.3  Conflicts with other Serial Devices
  1) Windows 95
     If you have problems operating other serial devices together
     with MouseWare, in Windows 95 run Regedit.exe, edit the key:
     n\Global\PortSearchOrder and remove the unused COM ports.
  2) Windows NT 4.0
     If you have problems operating other serial devices together
     with MouseWare, in Windows NT 4.0 run Regedit.exe, edit the
     s\Parameters\Global\PortSearchOrder and remove the unused
     COM ports.
  3) Windows 3.1x and DOS
     In Windows 3.1 edit the parameter "PortSearchOrder" in the
     [Global] section of the file MOUSEDRV.INI located in the
     C:\MOUSE directory and remove the unused COM port.
4.4  Power Management Problems
  If your mouse freezes when waking your PC up from suspend, in
  Windows 95 run Regedit.exe and edit the key:
  In Windows 3.1 edit the parameter "APMMode" in the [Technical]
  section of the file MOUSEDRV.INI
4.5  Logitech Enhanced Mouse Control Panel is not Updated
  Under Windows 95 if the Mouse properties has not been updated
