Run an application shortcut after an install

2006-02-02T15:24:45Z

L d allan: Add complete example in addition to 'snippets'

{{PageAuthor|jpannequin}}

== Description ==
Here is how to launch a shortcut at the end of an install (in the MUI). You may need this if you need to use a specific working directory and don't want to modify the MUI.

== Usage ==
So suppose I want to launch "C:\User\test.lnk".

Before calling the macro for finish, you must define the run variables.
If you define
<highlight-nsis>
!define MUI_FINISHPAGE_RUN "C:\User\test.lnk"
</highlight-nsis>
it will not work, because it is not an application.

You must set MUI_FINISHPAGE_RUN empty, and use a function instead.
<highlight-nsis>!define MUI_FINISHPAGE_RUN
!define MUI_FINISHPAGE_RUN_TEXT "Start a shortcut"
!define MUI_FINISHPAGE_RUN_FUNCTION "LaunchLink"
!insertmacro MUI_PAGE_FINISH
</highlight-nsis>
You can then define the function and execute the link with ExecShell.
<highlight-nsis>Function LaunchLink
ExecShell "" "C:\User\test.lnk"
FunctionEnd
</highlight-nsis>
