It looks like what you have is correct. You have a SAME_VERSION property. Although you might want to set OnlyDetect to yes if you want to keep the existing product there and not overwrite it.
Then, use a launch condition to stop the new installation from going through if SAME_VERSION is found. The new element, MajorUpgrade, does all of this for us, but that's how it's done by hand. -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/multiple-product-codes-returned-from-Upgrade-code-tp7598400p7598433.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
