Finally, the light at the end of the tunnel....
As I expected, turns out I used the FileSearch incorrectly.
Unfortunatelly, the WiX / MSI docs are misleading - or better said, the MSI
docs are pretty much almost impossible to use and understand from the first
read :)).
The fact that FileSearch is presented as a posible child of Property is a bit
unfortunate...
It has to be a child of DirectorySearch to get expected results.
Here is the code that DOES work as I intended:
<Property Id="FOUNDTABCTL32" Value="notfound">
<DirectorySearch Id="dirtosearch" Path="[SystemFolder]">
<FileSearch Id="filetosearch" Name="tabctl32.ocx"/>
</DirectorySearch>
</Property>
<Feature Id="ProductFeature" Title="MainFeature" Level="1">
<Feature Id="FeatureToInstallWhenOCXMissing" Display="hidden" Level="1">
<Condition Level="0"><![CDATA[FOUNDTABCTL32 <> "notfound"]]></Condition>
<ComponentRef Id="ProductComponent"/>
</Feature>
</Feature>

No , it still does not work as I intend.
Is it possible to use FileSearch to set a property
used in a Condition for a Feature or I started on the wrong road ?

Adrian,
I haven't tried this but what I would do is when you declare your Property -
omit the Value attribute.
This way the property will be undefined.
Then when you are checking use something like:
<Feature Id="ProductFeature" Title="MainFeature" Level="1">
<Feature Id="FeatureToInstallWhenOCXMissing" Display="hidden"
Level="1">
<Condition Level="0"><[FOUNDTABCTL32]></Condition>
<ComponentRef Id="ProductComponent"/>
</Feature>
</Feature>
This way when the FileSearch finds something then [FOUNDTABCTL32] will be
defined and the condition will hold, thereby setting the
FeatureToInstallWhenOCXMissing Level="0"
Tell me if this helps at all,
Alexei
