Hi Jamie, Yes, I was trying to ask if there was any major upgrade code implemented in the previous installer.

According to what I've read, it's just a simpler way of creating an Upgrade element. My understanding is that the only thing in the previous version that should be required is that it have the same upgrade code, as well as a ProductVersion property. The old version forced the user to uninstall if they had an even older version before installing. Here's the Upgrade section:<Upgrade Id="8D35ECC7-11D7-4471-B22E-581B8144B061"> <UpgradeVersion Maximum="99.99.99" Property="OLDPRODUCTS" MigrateFeatures="yes" /> <Property Id="OLDPRODUCTS" Secure="yes" /> <UpgradeVersion Minimum="99.99.99" Property="AI_NEWERPRODUCTFOUND" OnlyDetect="no" /> <Property Id="AI_NEWERPRODUCTFOUND" Secure="yes" /></Upgrade> There is this CustomAction:<CustomAction Id="AI_DOWNGRADE" Return="check" Error="A higher version of [ProductName] is installed." /> Then, in InstallUISequence, they had this:<Custom Action="AI_DOWNGRADE" After="FindRelatedProducts"><![CDATA[AI_NEWERPRODUCTFOUND]]></Custom> In InstallExecuteSequence, they had this:<Custom Action="AI_DOWNGRADE" After="FindRelatedProducts"><![CDATA[AI_NEWERPRODUCTFOUND AND (UILevel <> 5)]]></Custom> Still, my understanding is that the content of the Upgrade element on the old product is irrelevant when installing the new one. If I'm wrong about this, someone please correct me.
