I appreciate your help. The problem is that the installer is mainly used as
command-line without any GUI. The package gets pushed to several machines and
executed with several options (features) enabled or disabled, depending on
deployment automation schema. There might be 100+ servers involved. My
installer might be directed to deploy a feature that requires IIS but server
might not have it. In reality, the situation is even more complex as there are
other features that need to check for other prerequisites (i.e. MSMQ, specific
OLDB drivers etc).
I started leaning toward custom actions that can break installation process if
they cannot detect something they should. I wanted to avoid that hoping there
is something cleaner.
Thanks a lot.

You should set up the next button in the feature selection screen to display a
dialog that IIS is required for that feature(if selected).
MyCustomizeDLg is the dialog that has the list of the your features user can
select.
IISFOUND is a property you set to search for IIS present or not(I think WIX has
an in-built property to do this IISMAJORVERSION).
FeatureneedsIIS is the feature that requires IIS.
Something like this:
<Publish Dialog="MyCustomizeDlg" Control="Next" Event="NewDialog"
Value="IISNotFoundDlg"><![CDATA[NOT IISFOUND AND (&FeatureneedsIIS = 3 AND !
FeatureneedsIIS <> 3)]]></Publish>
In the dialog that shows the message to the user redirect the OK button to exit
dialog.
<Control Id="OK" Type="PushButton" X="102" Y="90" Width="56" Height="17"
Default="yes" Cancel="yes" Text="OK">
<Publish Event="EndDialog" Value="Return">1</Publish>
</Control>

Example: one of the features requires IIS. Check for IIS should occur only if
the feature is selected. If te check succeeds, the feature shall be installed.
If it fails, the installation shall fail. If feature is not selected the IIS
does not matter.

Can give an example so it will be easier to understand?
What are the conditions and what do the features depend on?

User can select any feature. Each feature has a different condition. Installer
verifies the condition for feature if it was selected for installation. If the
condition is not met, installer breaks and informs what was the reason.

"This Condition makes sense only if a particular Feature is being installed."
So, how do you plan to achieve this even before a feature is selected for
install?

Subject: [WiX-users] "Condition" problem
I need to define a Condition which generates message and stops installation (if
condition fails). This Condition makes sense only if a particular Feature is
being installed. It looks like I cannot use standard LaunchCondition because
checking for a Feature (using &Feature=3 or &Feature=4) can be used reliably
only after FinalizeCost, which happens after LaunchConditions.
Is there a way I can define such condition on a Feature level ? If not, what
is the best way to achieve the same outcome ?
Thanks a lot
