Windows components

From NSIS Wiki

Description

The following script example demonstrates how to Install/Uninstall windows XP components with NSIS. IIS (built in web/ftp server) is used in this example, with a few IIS sub_components. There is extensive documentation for other components and sub-components at the MS Website[1].

Windows XP uses a program called sysocmgr.exe to install components. Using an answer file it is possible to specify which components you need to add/remove.

The Code

ExecWait '"sysocmgr.exe" /C /i:sysoc.inf /u:C:\temp\answerfile.txt'

there are multiple switches that can be used as part of sysocmgr which include :

/i:<master_oc_inf>- (required) Specifies the name of the master inf.

/u:<unattend_spec>- specifies unattended operation parameters.

/c: - disalow cancel during final installation phase.

/x - suppress the 'initializing' banner.

/q - for use with /u: Runs unattended without UI.

/w - for use with /u: If reboot is required, prompt user instead of auto reboot


When using /u: for unattended you must specify an answer file with the parts you need along with its relevant path. Again, the MS website [2] is the best place to go - as different components would need different sub components.

The answer file would look something like this :

Answerfile.txt

[Components]
iis_common=on
iis_ftp=on
iis_inetmer=on
iis_smtp=on
iis_internetdataconnector=on
iis_www=on
inetprint=on
 
[InternetServer]

In this case the answer file stipulates that we only want to add the listed iis components and internet server.

Uninstalling Components

The exact same command and switches can be used to uninstall components. All that needs to be done is the answer file should specify <component>=off. For example

[Components]
iis_common=off
iis_ftp=off
iis_inetmer=off
iis_smtp=off
iis_internetdataconnector=off
iis_www=off
inetprint=off
 
[InternetServer]
