Setting reboot options
You can force or prevent the target computer from restarting during the
installation. To do this, add the REBOOT property to the command line.
REBOOT=F forces the restart, while REBOOT=R prevents the restart. If you
must first install the Windows Installer service on a target computer, Setup
will require you to restart whether you force or prevent a restart for other
reasons. Setup will resume after MSI forces a restart. It will then use the
options you set to determine whether to force or prevent a restart after the
installation.
setup REBOOT=R /q /i
This example runs a silent installation and prevents a system restart.
Setting security type for Windows NT
If you install VirusScan software on Windows NT Workstation v4.0 or
Windows 2000 Professional systems, you can choose to run the software with
regular or maximum security. To set this value from the command line, run
Setup with the USEADMINONLYSECURITY property and the value you
want to use.
To run the software with standard security, give the property the value 0:
USEADMINONLYSECURITY=0
To run the software with maximum security, give the property the value 1:
USEADMINONLYSECURITY=1
To use the property from the command line, type a line similar to this:
setup USEADMINONLYSECURITY=1 /q /i
This runs a silent installation and sets the security level so that only a user with
administrative rights can configure or stop the product.
Removing incompatible software
By default, Setup removes incompatible software during a silent installation.
To prevent Setup from removing incompatible software, add the property
REMOVEINCOMPATIBLESOFTWARE to the command line with the value
False:
setup REMOVEINCOMPATIBLESOFTWARE=False
