Initializing help system before first use

# Silent Installations

Many of the options here are substitutes for actions that can be done via the installer UI that means they can be specified in a script and run without user intervention.
When using this option, it is worth taking a log, using the "/v /L" or "/v /Log" options mentioned in Available Options When Using msiexec.exe in the previous section Command Prompt Options, in case any problems are encountered. The installer detects that the procedure is intended to be silent and will not show any error message dialogs.
Note: Logging directives are omitted for space and clarity in the following section. You should to specify a log file when performing silent installation operations.
Two directives are needed for a truly silent installation:

Directive | Description
/s | Installer option will hide the opening dialogs as the installer is being unpacked before running
"/v /quiet" | msiexec option suppresses the UI for the rest of the installation

To perform the equivalent of a Custom install silently, use the `ADDLOCAL` option defined earlier to set which parts of Xpress Insight are included. The options are:

- `Server` for the Insight Server
- `Worker` for the Insight Execution Worker

If `ADDLOCAL` is not specified, all of Xpress Insight will be installed. To install everything except specified element, set `ADDLOCAL` to the special value `ALL` and `REMOVE` to the element names:

    /s "/v /quiet ADDLOCAL=ALL REMOVE=Worker"

Note: This may become more useful as and when more elements are added to the installation. Multiple elements for the `ADDLOCAL` or `REMOVE` value can be listed sequentially separated by commas. For example, " `/v ADDLOCAL=Server,Worker`"
