Table 4. List of parameters with -a
Parameter Description Example
/s This parameter is used for silent mode.
It suppresses the initialization window
defined in the installation file to execute
after the extraction. [Update Retriever installation
file name].exe -s -a /s
/v This parameter passes the command line
switches and values of public properties
to the MSI file included in the installation
file. This parameter is used to suppress
the MSI file user interface. You would
use this parameter in conjunction with
other parameters and the executable
file that the installation file will start
after the extraction when you want to
do a silent installation. You can pass
information to the MSI file using the
command line to execute the installation
file. All parameters within the double
quote marks (" ") after the /v parameter
are passed to the MSI file. [Update Retriever installation
file name].exe -s -a /s /v" /qn
/L This parameter specifies the language
used by a multi-language installation
program and requires a decimal language
ID. A decimal language ID corresponds
to an identifier in the table. See System
Update language codes. [Update Retriever installation
file name].exe -s -a /s /v"
/qn" /L1033
The above command line will use English.
/w This parameter forces the executable
defined in the installation file to execute
after the extraction and to wait until the
installation is complete before exiting. [Update Retriever installation
file name].exe -a /w
If you extract the installation file contents first, and
want to use the /w parameter with the executable,
the installation file will point to the folder where file
contents are extracted and then start the executable
file specified in the installation file as the executable
file to start after the extraction, for example:
Setup.exe /w
reboot=r" This parameter suppresses the reboot
request during the process of clean
installation, upgrading or over-installation. [Update Retriever installation
file name].exe -s -a /s /v"
/qn reboot=r"
Installation log file
The installation log file contains information that can be used to debug installation problems. For System
Update, the log file name is tvsusetup.log; for Update Retriever, the log file name is tvursetup.log.
If you install the program by double-clicking the setup.exe file, the log file will be automatically generated and
stored in the %temp% directory.
If you want to install the program silently and generate installation log files, use the following commands:
• For System Update:
[System Update installation file name].exe/VERYSILENT /NORESTART/LOG=c:\tvsu.log
To specify the detailed log directory, use the /LOG command.
• For Update Retriever:
