WIX Version: 2.0.4415.0 Problem Summary: How to prevent pre-existing
registry keys from being removed during uninstall. I’m still quite new to
WiX so please bear with me. I am trying to understand a scenario. I am going to install an
application that will create some registry entries but will also update some
that already exist. During the uninstall all registry keys are removed. I
need to keep any that already existed. Here is a simple script that
shows what I’m talking about. To test it, simply create a README.TXT
file for it to install. Also, manually create a registry key in HKLM\Software\Acme
called ‘SomeIntKey’. The key is a DWORD so set its value to any
non-zero value. If you install the MSI
created with this script then the registry key is changed to 1 (that’s
good). Now uninstall the MSI. The key is removed (that’s bad)! How do I prevent the key
from being removed during uninstall? <?xml version='1.0'?> <Wix xmlns='http://schemas.microsoft.com/wix/2003/01/wi'> <Product Id='457E3468-BA41-47bd-83A8-F6D44B282171' Name='Test Package' Language='1033' Version='1.0.0.0' Manufacturer='Acme,
