& is a feature-action, and ! Is the current feature state, so I am
checking both the existing state and what the installer is going to do
(ie IF (Not Installed and Not Going to Be Installed).
In this case I want the CONFIGURE IIS to run both on install, upgrade
and repair.
I often use the combination for Custom Actions to say FeatureState is
Absent and FeatureAction is Local for running once on install. And
vice-versa for the uninstall.
As I understand it, it is fairly important to consider both. (Its also
important that this run after CostFinalise.)
I suppose with your database deletion issue you could have used the
condition of !DBFEATURE=3 and &DBFEATURE=2 (the database feature is
going from installed to uninstalled (absent).
More detail is in the MSI SDK on Conditional Expressions.

Thanks Michael, it worked !
One question: I have noticed that you've used &MainComponent and
!MainComponent Can you tell me what's the difference between the two and
is it important to use two of them together?
Thanks.

Try looking at the SKIPCONFIGUREIIS property (its part of WIX), this
is how I stop the installer from doing the IIS Custom action if
MainComponent is not selected.
<!-- Suppress the IIS CA if we are not installing the
web site -->
<CustomAction Id="SkipIISCA" Property="SKIPCONFIGUREIIS"
Value="1"/>
<InstallExecuteSequence>
<Custom Action="SkipIISCA"
After="CostFinalize"><![CDATA[NOT &MainComponent=3 AND NOT
!MainComponent=3]]>
</Custom>
</InstallExecuteSequence>

Subject: [WiX-users] How to skip a custom action when feature not
selected
My installer creates a website during the product installation. I
would like to add a feature to the installer to enable the user to
skip the website creation and I thought about using something similar
to that:
<Custom Action="ConfigureIIS" Overridable="yes">NOT Installed AND
<![CDATA[&IISFeature=3]]></Custom>
But I get an error message saying that a Custom element must have a
Before attribute, After attribute, or a Sequence attribute.
I don't want to change the sequence of this action and I really don't
care what is the sequence. All I want to do is to skip the creation of
the website by skipping the custom action ConfigureIIS.
Do you have any other idea?
