WiX InstanceTransforms element produces unresolved reference

I am trying to create a multi-instance setup and followed this question and answers to make it:

Use WIX to install side by side versions of the same IIS site

So I inserted this to my product.wix file

<InstanceTransforms Property="INSTANCEID">
  <Instance Id="I01" ProductCode="{68E8345E-0B22-479C-B7A5-7D1B3DC2F835}" ProductName="My Product 01"/>
  <Instance Id="I02" ProductCode="{A0E37B8D-12AB-42A0-8F11-9CB08F54B9DE}" ProductName="My Product 02"/>
</InstanceTransforms>

However, when I build my setup project, I get this error:

Unresolved reference to symbol 'Property:INSTANCEID' in section 'Product:{38EEE9BE-86BF-49FB-813B-953DD945575E}'.

Where 38EEE9BE-86BF-49FB-813B-953DD945575E is my main Product Id. I could not find any reference to this error in the InstanceTransform scope. What am I doing wrong?

UPDATE: The first thing I tried when I got this error was of course creating a property inside my product with that is called INSTANCEID and some value. However, the error persisted.

I added the Yan's code from his comment below and it compiled. I am not sure what was wrong with my property.

Solution

  • You need a Property element with the Id of your InstanceTranforms/@Property value.
