That's not the case.  I'm installing it on the same machine logged in as the 
same user.  I guess my question is, what is the ProductCode, where is it set?  
Here's my Product element, what should be changed so that it knows that this an 
upgrade to a product that is already installed?

    <Product Id="*"
             Name="My App $(var.BuildVersion)$(var.BuildNameSuffix)"
             Language="!(loc.Language)"
             Version="$(var.BuildVersion)"
             Manufacturer="Me"
             UpgradeCode="75DD6EF7-EDDE-40D1-A997-170A8419A4E4"
             Codepage="1252" >

Ah, the other explanation is that you installed that MSI in a per User context, 
and now you're installing it a different user context (another user or per 
System).

Yes, the Installed property means "this ProductCode is installed". If you see 
that Welcome dialog again the most obvious thing to check is whether the 
ProductCode has changed. The idea is that you only see the Welcome dialog on 
fresh first time install. Later actions based on the same ProductCode are 
maintenance options, feature add/remove etc.

It's got to be the ProductCode changing. This stuff works all the time and has 
done for years. This is a Windows Installer property used in every MSI-based 
install, whether WiX or not. It's not likely that such a basic thing doesn't 
work.

So what property is it actually checking to see if it's installed?  On my 
product element there is a Version attribute and there is an UpgradeCode 
attribute, are these what are being used?

Again I have already installed the product and when I run the installer again 
(with the Version attribute change to a higher minor version) this dialog still 
shows.  I actually want the dialog to show but I am just curious as to why it 
is still showing given this criteria.

Thanks.

It means an MSI sharing this ProductCode  ( either this PackageCode which would 
indicate a maintenance transaction or another PackageCode which would indicate 
a small or minor update ) is already installed.  In the case of a Major Upgrade 
the ProductCode has been changed and therefore from this new MSI's perspective 
it is not yet installed.

&  is a special operator regarding features.  See the links I sent in my other 
email.

As far as I understand it, "Installed" means, "Before this installer was run, a 
version of this program was already installed on this machine".
Someone please correct me if that isn't quite true.

As far as &ftDatabase=3, I have no idea, I haven't yet seen that syntax yet.

Subject: [WiX-users] Question about conditional statements in elements

I'm very new to WiX and have inherited an existing project.  I've been 
deciphering it fine except for a few things.  In this project I have the 
following element:

<Show Dialog="WelcomeDlg" Before="ProgressDlg">NOT Installed</Show>

The question with this is the "NOT Installed" condition.  What exactly does 
"Installed" mean?  When I run this to upgrade and already installed application 
this dialog still shows up. SO, I'm not sure what Installed really means (there 
is also an Upgrade element in the project with a property assigned to it that 
is used in other controls throughout the project).

Next is the following syntax that I have in several control conditional
statements:

&ftDatabase=3

The ftDatabase is the ID of one of the Features.  However, I don't know what 
value it would have.  Is this an install level value or install type value?

Thanks for some newbie help.
