Hey, Thanks for replying!
Perhaps I should provide some more information... I am helping out with creating an OSS project called ChocolateyGUI. This involves creating an MSI package, which is then wrapped into a nuget package, and then which is available in install from chocolatey.org. The nuget package includes both an install and uninstall PowerShell script, which are then invoked from the chocolatey “engine” when required. To that end, in order to create the uninstall script, I was hoping to include the product code in the uninstall script. However, since it sounds like the Product Code is not easily known, I am thinking that I won’t be able to use this approach. I have “got around” this by using the LocalPackage location from the registry key that is created to uninstall the package, but not sure how “reliable” this is. This does bring up another question, and was hinted at in the other response to this question: “If you plan an upgrade, why do you need ProductCode of the previous version ?” What is the best approach here? We are going to be shipping updates to the product. We are currently working on version 0.11.0, but this will be closely followed by 0.12.0. Should I fix the Product Code, and simply uninstall the previous version. If so, what is the norm when doing this? Sorry if this is naïve, but only really just getting started with creating and maintaining msi.

I have implemented the following pattern: http://wix.sourceforge.net/manual-wix3/major_upgrade.htm I allow for ease of upgrade. However, the installation package that I am trying to create needs to know about the ProductCode, in order to pass a parameter to the msiexec to make it uninstall the app. Since I am using Id=”*”, how can I find out the correct ProductCode (i.e. GUID), in order to pass as a parameter to msiexec.
