Kevin, Lesson 4 is/was based on Wix V3. Rob's reply refers to an addition to Wix3.5 though I would expect lesson 4 code probably still applies in V3.5. Depending on which version of WiX you use will determine what options you have for writing upgrades.
Now, the key is where you place the RemoveExistingProducts function as this directly affects exactly what happens. If you schedule it early in the sequence then any existing product is uninstalled in its entirety before your new version is installed. If, as you have, schedule it late in the sequence then basically what will happen is that the initial install will remain with only files that have changed being affected/changed/removed. A quick search for RemoveExistingProducts should you the location to schedule it early or late (I don't remember the location off the top of my head). Note, there are advantages and disadvantages of using it either way so you may also want to look into that and decide which suits you best. If you are having specific issues with upgrading, can you be more specific about what is, or isn't working? Creating a verbose log when you run the installer may also help you diagnose what's happening. Chris On 02/25/2011 11:05 AM, Kevin Burton wrote: > What is the syntactic sugar?
