• For Update Retriever: %PROGRAMFILES%\Lenovo\Update Retriever Installation procedures and command-line parameters System Update and Update Retriever can use the same command line parameters for installation. The following example starts a non-silent command line installation for System Update or Update Retriever. c:\>[System Update installation file name].exe To do a silent command line extraction followed by an installation, use the /VERYSIELNT parameter. The extract defaults to the Windows Temp folder, for example: c:\>[System Update installation file name].exe/VERYSILENT /NORESTART To silently extract to a specific folder followed by an installation, use the DIR parameter, for example: [System Update installation file name].exe/VERYSILENT /NORESTART/DIR="C:\TVT\tvsut" The /DIR parameter causes the files to be extracted to the c:\tvt\tvsut folder. You can use the -e parameter to extract the contents of the installation file. If you want the Update Retriever installation file to start the executable, specify the file name after the -e parameter, for example: -e[Update Retriever installation file name] The following table provides examples where the file name is not specified. Table 3. Extract command scripts Product Command line Update Retriever UpdateRetriever-setup.exe -fc:\tvt\tvurfolder -e Comment Extracts Update Retriever to c:\tvt\tvurfolder Extraction folder c:\tvt\tvurfolder\setup.exe List of parameters The application is packaged as a self-extracting installation file. Therefore, the Update Retriever installation file specifies the executable to start after the extraction. If you use the -a parameter, then any parameter following the -a will be passed to the installation file executable, and then prompts the execution to start after the extraction, for example: c:\>[Update Retriever installation file name].exe -s -fc:\tvt\tvsut -a [list of parameters] The following table provides the parameters used with the -a parameter.
