Hi David, Yes, it's possible, but probably not quite as you've described it. What you're looking to do is an upgrade to the application. You can release this as a full MSI that performs new installs straight to the new version and will also update any old installs, and efficiently handles which files are copied etc. However, doing so will require you to do quite a bit more reading to fully get to grips with the underlying MSI technology to support this.
If you haven't already, download and install the MSI 4.5 SDK, and in the MSI.CHM file search for Upgrade and read everything you can find, which will include an example of upgrading a package. Depending on what you're changing in your package you may also want to look into the Component rules, including entries like Changing the Component Code. You'll probably want to do a Major Upgrade, and make sure you take advantage of what's described in Preventing an Old Package from Installing Over a Newer Version. Also, be careful with the sequencing of your uninstall of the old version, see the help file entry for the RemoveExistingProducts Action for more details.

Subject: Re: [WiX-users] Domain Install As an update, the suggestion about the type 35 CA that James gave me worked great and everything was good for deployment, but during the final acceptance testing, I had a new requirement placed on me which set me back a few steps and I need some additional advice. Is it possible (and if so, how) to have a package determine if a previous version is installed, and if not, install all the components (say #'s 1 through 20), but if it is, then update a select subset of components (say #'s 8, 10, and 17) with the new component version? In essence, they want me to do is combine a minor patch and a full install into a single package with the intelligence to know which action to take based on the state of the machine it is run on.
