Download Windows 9x, ME, 2000, XP drivers v 5.41 (ssd5410-32bit.exe, ~4.3Mb)
This is a single executable installation file. We recommend that it be downloaded into a previously created directory titled c:\isl.

After downloading, run the file c:\isl\ssd5410-32bit.exe... it will install into...
c:\Program files\Rainbow Technologies\Sentinel System Drivers\..., and will then automatically install the new drivers.  Just accept all the prompts including the request for 'Complete' installation. 

The drivers will be installed by the Microsoft Windows Installer (MSI).  If MSI is not already loaded on your machine, it will be loaded automatically as part of the installation, but it may require one or more re-boots.  Just follow the prompts.  

If the installer detects a previous Sentinel driver version, it may remove it automatically, or may ask that you remove it manually, or it may ask if you wish to modify it... depending on the version.  If manual removal is requested, use the Control Panel 'Add/Remove Programs' utility to remove all references to 'Sentinel System Drives' or similar.  This may require a reboot; thereafter re-run c:\isl\ssd5410-32bit.exe

After the drivers have been successfully installed, the temporary file c:\isl\ssd5410-32bit.exe can be archived or deleted.

Download Windows NT4 drivers v5.41 (ssd541legacy.exe, ~240Kb)
This is a single self-extracting WinZip file. We recommend that it be downloaded into a previously created directory titled c:\isl.

After the file have been successfully unzipped, run setup.exe from the \Legacy directory, i.e. ...

This file does not load the Microsoft Windows Installer (MSI)

Downloading, Decompressing and Installing the Drivers v5.38

Download Windows 3.1x Sentinel Drivers (~drv538.exe, ~400Kb)...
This is a single self-extracting executable file which will decompress into several sub-directories. We recommend that it be downloaded into a previously created directory titled c:\isl.

After downloading, run the file c:\isl\~drv538.exe... it will decompress into...
c:\isl\drv538\win_31\...
c:\isl\drv538\win_9x\...
c:\isl\drv538\win_NT\...

After decompression, you will be asked if you wish to install the drivers immediately, or defer their installation until later. We recommend immediate installation. 

If a floppy backup of these drivers is required, then copy all files in c:\isl\drv538\... and all its sub-directories onto a single disk. Label the disk 'Portable Sentinel Drivers v5.38'.

After the drivers have been successfully decompressed, the temporary file c:\isl\~drv538.exe may be archived or deleted.

If the drivers were not installed following their decompression, they can be installed at any time later either automatically or manually. We recommend the automatic method.

• Automatic Installation (quiet mode)
  Just run c:\isl\drv538\setup538.exe. This auto-detects which operating system being used, and installs the relevant drivers. It is completely silent, requires no user intervention, and takes only a few moments. Just wait until the hourglass disappears. Restart Windows on completion.

• Semi-Automatic Installation (with user intervention)
  To install the drivers semi-automatically (with some user intervention), use the /q4 command line switch, e.g. c:\isl\drv538\setup538.exe /q4. This auto-detects which operating system being used, and installs the relevant drivers, but also allows some user control of the process. Re-start Windows after installation.

• Manual Installation.
  The drivers are supplied in three directories. Select the appropriate directory for the operating system, then run one of the following...
  c:\isl\drv538\win_31\install.exe
  c:\isl\drv538\win_9x\sentw95.exe
  c:\isl\drv538\win_NT\setupx86.exe
  Re-start Windows after installation.
