Launch application after finish checkbox is missing from SdFinish dialog

[jack_z_2000]

I'm creating the InstallScript MSI project. in dialog sampler view, the SdFinish dialog wouldn't display the "Launch application after finish" checkbox even though it was available in the resource file, how can I make it visible? I tried to change the control property, but it didn't work.

Thanks.

Set bOpt2 and szOpt2 on the OnFirstUIAfter event handler,for example:

bOpt2 = TRUE;
szOpt1 = "Launch my application";

if ( bOpt2 ) then
//LaunchAppAndWait(......);
endif;

I tried, but it didn't work. The checkbox is still not showing up.
