Link to details about how to use new patch creation features in WiX v3.0

  • Artigo

Peter Marcu posted a couple of items on his blog recently that I wanted to link to here so hopefully more folks will see them.  The first is a high-level description of new patching features that have been added to WiX v3.0 over the past few months.  You can find the post at https://blogs.msdn.com/pmarcu/archive/2007/06/16/wix-building-a-patch-using-the-new-patch-building-system-part-2.aspx.  It briefly introduces the old and new ways to create patches using WiX.

The second is a really nice example of how to create a patch using the new features in WiX v3.0.  You can find this blog post at https://blogs.msdn.com/pmarcu/archive/2007/06/28/sample-patch.aspx.  To summarize Peter's post, the following are the steps that can be used to create your first patch:

  1. Create your initial product layout file/folder structure
  2. Create a new copy of the product layout (called an upgrade layout) with patched files included in it
  3. Create a WXS file that can be used to build an MSI for the product layout in steps 1 and 2 above
  4. Create a WXS file that can be used to build an MSP for the patch
  5. Build a .wixout and .msi file for the initial product layout using Candle and Light
  6. Build a .wixout (and optionally a .msi file) for the upgrade product layout using Candle and Light
  7. Create a .wixmst (transform) file for the differences between the 2 layouts using Torch
  8. Build a .msp (patch) file that will apply to the .msi file created in step 5 using Candle, Light and Pyro

If you are a setup developer interested in creating patches for your MSI-based installers, I encourage you to check out Peter's blog posts for more detailed information about how to use new features in WiX v3.0 to create patches.

<update date="7/17/2007"> Updated step 7 to indicate that the output file is a .wixmst file and not a standard Windows Installer .mst file </update>

    Actually, in step 7 you create a wixmst, which is just a wixout for transforms. The extension doesn't matter really, of course. A wixout is perfectly acceptable.

    Hi Heath - Good catch, that was a typo when I was summarizing Peter's list of steps.  I've updated the text of my blog post with this to avoid confusion.
