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

[Hoover, Jacob]

Multi-Instance installations (ala instance transforms) are nasty and painful. You are going to need to make your decisions before you are running your MSI.  Sadly, we don't have burn support out of the box for instance transforms.  I'm not saying it's impossible, but you are almost certainly going to have to create a custom BA to handle this.

Well i know that, the thing is that the application can be installed multiple times on the same machine.
So there for I need to be able to choose if I want to update an existing installation, and which one, or do a new installation.

Hi,
You can do all this automatically without writing your own dialogues etc.

The Major upgrade pattern allows you to release version 1 of your installer, make some changes to it, increase its version and version 2 will upgrade if version 1 is present or clean install on a blank machine.

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.
Ronny Eriksson
