Installer almost silent

Hello everyone:

I have my installer created that it's completely silent, I have included this line at the beginning of my file:

SilentInstall silent

Now, the only thing I would like to get is that once the installer is done, pop-up a little message saying, installation completed, with no details or anything, just a message box.

thanks.

Just as you mentioned, a message box (without any /SD switch) recommended in function .onInstSuccess.

Thanks!
