WIX upgrade only the version and not the installed files

I have an installer with <Product Id="GUID" Version="3.4.1.15".... The installer will run custom actions is distributed to customers.

Am trying to created a update/upgrade/patch to the msi (Version = 3.4.1.16). The new patch should execute actions only the new actions, that are part of 3.4.16.

Below is the code that I tried to achieve this. (changed ProductId="*" and tried AllowSameVersionUpgrades="yes".

The installer goes to Major upgrade mode, however, the Installer is doing the following Sequence.

  1. Remove version 15
  2. Upgrade the Product code of 15 to product code 16
  3. Install product 16 as fresh install.

So all the fresh install scripts are executed again during the patch process.

Below is the sample Test package that illustrates what am saying.

The requirement is to Run Step 2 alone for 3.4.15 to 3.4.16 & Run Step 1 & 2 for fresh install of 3.4.16

The steps I have taken may not be the right ones. Kindly help to achieve this.

Thanks

Solution

  • Major upgrade is the uninstall->install. If you want to change existing installation, you should use patch.
