What is the switch for performing a silent install of Messenger Plus version 5? 

/Silent worked in version 4.x and it didn't install any sponser programs either.

Thanks Sam for trying it on your system.

This is the command i'm running from a .bat .cmd script or command prompt, on a windows XP SP3 that already has version 4.x installed.

Setup-MsgPlus-501.exe /Silent

It opens the messenger plus! welcome screen and waits for me to hit next.

Maybe I should uninstall version 4 first?

Hm,

I'm not sure if the /Silent requires an uninstallation of version 4, however I suggest you do try, as the default installation folder has indeed changed from v4 to v5 (C:\Program Files (x86)\Yuna Software\Messenger Plus!)

Beyond that, unless I'm forgetting something the command should work .

/Silent should indeed work (I just tested this) with the normal offline installers.
Though, it will not work with the current webinstaller.

However, note that it isn't completely silent anymore since a webpage will be opened at the end of the install to thank the user for installing (I suspect this is the wrapper's fault - more on that below).

Plus!4 being installed or not shouldn't matter.

Another parameter you should be able to use is /Destination=directory.

And then there is /? or /Help or -help.
However, this parameter apparently doesn't work anymore*.

* That is, it still works but only on the actual setup file itself. It does not work on the wrapper of the setup file. And it is this wrapper which is actually downloaded from the official download page as being the so called 'setup'. But thus in fact, the real setup is wrapped within it. Hence there is a problem/bug in the wrapper as it doesn't pass on the command line parameters to the actual setup. At least not the /help parameter; The other parameters are being passed on.

Note: Plus!4 didn't had an extra wrapper around its setup like Plus!5 has.

Note: You can find the setup file in a subdir in your temporary files folder when you start the Plus! installer.

** The webinstaller has some other command line parameters as well, but those are only used internally though.

I didn't realize that there is a web installer and a normal installer.   However the only download that I can find for version 5 is for the Setup-MsgPlus-501.exe which is only 419 KB and obviously the web installer.

Where do I find the normal installer? 

http://mirror10.msgpluslive.net/20110308/Conduit/Setup-MsgPlus-501.exe

That's the download link for the full setup with the optional "Conduit" sponsor.

Hurray - The /Silent switch is working again.  Thanks everyone, especially CookieRevised for the information regarding the differences between the web installer and the normal installer, and Articwolfx for the download link for the normal installer.  Perhaps in the future the link for the normal installer could be located were it will be easier to find?
