The silent install for the Windows client requires two switches, or command line parameters. These are /S and /D=. The path should be substituted with the path to the desired installation location.
This is an example:
y:\labstats\labstats_windows_client_installer.exe /S /D="c:\program files\labstats"
Quotes should be used when the path includes spaces. The labstats.conf file must be present in the same directory as the client installer.
To uninstall silently, you run the command "C:\program files\labstats\uninstall.exe" /S
If you have installed the client in a different location, then you would replace "C:\program files\uninstall.exe" with the full path to the LabStats uninstaller.
