HP Virus Throttle for Windows License Utility 3 

HP Virus Throttle for Windows License Utility 
The HP Virus Throttle for Windows License Utility (VTLicense) can be used to add a ProLiant Essentials Intelligent 
Networking Pack Windows Edition license to the system or display licenses previously installed on the system. This 
utility is a Windows®-based command line utility and can be run at the command line of a Command Prompt 
window or from a Windows command file. 
Overview 
The VTLicense command validates that the license is a proper ProLiant Essentials Intelligent Networking Pack license, 
and if it is valid, adds it to the system. It then writes the results to a default log file (VTLicense.log) in the 
%SystemRoot%\cpqsystem\log directory. All successful and error messages are written both to the stdout/stderr and 
to the log file. The log file is appended with each invocation of the utility with the date and time stamp. The default 
log file can be overridden by the user by specifying a log file using the /l option. 
The utility parses the command line and if the license and the action are valid, it performs the desired action. Because 
this is a command line application, it is appropriate for inclusion in the GuiRunOnce section of unattend.txt and can 
be used to add a ProLiant Essentials Intelligent Networking Pack license during installation of the operating system. 
IMPORTANT: The Virus Throttle for Windows License Utility (VTLicense) should be executed before running the 
VTINSTALL utility to install HP Virus Throttle on your system.
