Change Wix Merge Module Package GUID?
- by jenglert
When is it necessary to change the package GUID of a merge module?
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
<Module Id="MyMergeModule" Language="1003" Version="1.0.0.0">
<Package Id="SOME_GUID" Manufacturer="Me" InstallerVersion="301" />
</Module>
</Wix>
Wix3 requires that the package GUID is explicitly specified for a merge module unlike for a product. My merge module will be used with an MSI that is built bi-weekly. These bi-weekly MSIs need to co-exist on the same machine as separate installations (e.g. versions 1, 2, 3, etc...) Do I need to change the package GUID of my merge module for each bi-weekly MSI build?
