Prerequisites for using DriverInst:
- Close Watcher
- There is an 'Installer_parameters.xml' file in the same directory as DriverInst.exe
- There is a 'Drivers' directory in the same directory as DriverInst.exe

Command line options:
-r    : uninstall drivers from system
-s    : Silent Mode; no UI
-w    : Wait on hardware wizard to finish before returning
-phww : Bypass the new hardware wizard running check
-xml=xxx.xml             : specify an xml file to use to orveride the default value of installer_parameters.xml
-pid=XXXX...[,XXXX...]   : to install a specific device drivers identified by PID value of XXXX (minimum of 4 bytes)
-ndis620                 : Install NDIS 6.20 drives on Windows 7 machines
-noloc                   : Do not install location driver for Windows 7 machines 
-rs                  	 : Uninstall the driver from system and them rescan the devices
-dis=XXXX...[,XXXX...]   : to disable before install/Uninstall and then reenable a specific device identified by PID value of XXXX (minimum of 4 bytes)


Usage example: C:>DriverInst
               C:>DriverInst -xml=HSPA_devices.xml
               C:>DriverInst -pid=68A0,6880           //This will install drivers for Direct IP devices and C885 only

Post-affects:
- logging is available in application data (Creates an 'Driver_Installer.txt' file with installation details)



Note for 64-bit machines:
Always launch DriverInst.exe and not DriverInst64.exe on 64-bit machines.
This is because DriverInst.exe detects what OS (32/64 bit) it is running on
and automatically launches DriverInst64.exe if a 64-bit OS is detected.

Troubleshooting:
If you notice any problems after running DriverInst to install drivers for your
device, try running DriverInst with the uninstall option ('-r') before running
it again to re-install your drivers.
