[wix-users] How to control what files to be installed (Condition)

You'd need to put the condition in each Component.  If there is a separate Feature for all the conditional components, you will also need a condition for the feature.

Note that the condition is not evaluated each time by default.  If the property values controlling the condition are very changeable, you'll need to mark the component transitive which has its own consequences.

Hi Eveyone

So i'm not sure if this is possible or not but i ask anyway to see if anyone of you have a solution for it because i can't figure it out.

What i want to do is this.
I want to have a dialog that askes the user if this is a new install or an update of existing installations.
This dialog is not the problem.
But how do I then control what files are installed when choosing the new install or the update existing option?

Can i somehow do a condition on what ComponentsGroupRef/ComponenRef that will be used or something like that and if so how can I do it?
I know I can't do this:
      <ComponentGroupRef Id="MyNewInstallFiles" ><![CDATA[NEWINSTALL]]></ComponentGroupRef>
      <ComponentGroupRef Id="MyUpdateFiles" ><![CDATA[UPDATE]]></ComponentGroupRef>
But that it's essentially what I would like to do... if you understand what I'm think of here.

Any example would be appreciated.
