I have tried that but, it doesn't work. It seems that the MSI evaluates the feature condition during CostFinalize. As CostFinalize takes place before my UI sequence, so any property change has no effect on the install behavior. So, looking at other similar references, I took a different approach. I set my feature's default install level as '1' (i.e. to be installed). In the UI control, I am removing the feature depending on the property value:
<Control Id="NextButton" Type="PushButton" X="250" Y="300" Width="60" Height="20" Disabled="no" Text="Next" Default="yes"> <Publish Event="Remove" Value="MyDoc"><![CDATA[MYPROPERTY = 0]]></Publish> <Publish Event="EndDialog" Value="Return"><![CDATA[1]]></Publish> </Control> But curiously, if I do so, my installation starts failing. If I comment out the 'Remove' event statement above, it installs fine. But, it installs the feature too, that I don't want to install (as I have that feature's level set to 1). I am not sure why the '<Publish Event="Remove" Value=...' statement makes the installation start failing. Any ideas on how to do that... Thanks.
