Richard Here's some help on doing upgrades
http://blogs.technet.com/b/alexshev/archive/2008/02/15/from-msi-to-wix-part-8-major-upgrade.aspx Looking at your code, I think you may have sequenced RemoveExistingProducts in the wrong place. It either needs to be <InstallExecuteSequence> <RemoveExistingProducts After="InstallValidate" /> </InstallExecuteSequence> or <InstallExecuteSequence> <RemoveExistingProducts After="InstallFinalize" /> </InstallExecuteSequence> The first option removes all the files regardless then installs the newer versions. The second only removes those files that have changed between the two. I believe there are pros and cons to using one method over the other but I am not the person to tell you what they are (I use the first option in my installs). You also need to make sure your product code changes from version to version but the upgrade code must remain constant through all versions. You can also use the verbose log during an install to see what's going on. The output can seem a bit cryptic initially but it can help debug the problems. Finally, you might want to consider adding a check to prevent people downgrading. The link I sent has information on how to do that.
