MSI silent installation problem

Hi

I have an application that have to be installed in silent/passive mode. The
first installation goes well. When I try to execute a silent/passive
installation of the new version (new msi version), the application files are
updated but in the Add/Remove Program interface, there exist 2 instances of
the application for each of the msi (even though there is only one instance
installed on the computer). On the other hand, when I execute the new version
in full UI mode, everything goes well.

any ideas..

Thanks in advance!
 
Silent installs default to per-user (just me) and your original install with
UI was probably per-system (Everyone). One won't upgrade the other, so you
end up with two products installed. I suspect that's what's going on. The
simplest thing for you to do iis use VS 2005 - its setup projects have a way
to set the per-user/per-system setting so you can ensure both setups are the
same. Does it work if you run your upgrade setup with a command line with
ALLUSERS=1 at the end, assuming your first install was "Everyone"?
(ALLUSERS is case-sensitive).
