[Option] librarypath [Example/Description] 
libinst.console update c:\...\library_folder This variable is required. This is the directory where you want the update files to reside, OR, where they currently reside if you do not have a separate location. If your update files already reside in this directory, you may not need any other options to update your library. If your update files reside in a different directory, you can either copy them into this location yourself before running LibInst.Console, or, use the /sp option and have LibInst.Console copy them for you. This must be an existing directory. LibInst.Console will not create it for you. The path must be to writable media. During an update, the latest library install file and any updates are copied or downloaded to this location. This path cannot change after you install the library. This will retrieve any update files and Library.libinst.
