<!-- AllowSameVersionUpgrades -> Always upgrade, never allow two versions to be installed next to each other -->
<!-- AllowSameVersionUpgrades causes ICE61 which must be ignored -->
<MajorUpgrade Schedule="afterInstallInitialize" DowngradeErrorMessage="A newer version of [ProductName] is already installed. Setup will now exit." AllowSameVersionUpgrades="yes"/>
