    AllowSameVersionUpgrades:
      When set to no (the default), installing a product with the same version and upgrade code (but different product code) is allowed and treated by MSI as two products.
      When set to yes, WiX sets the msidbUpgradeAttributesVersionMaxInclusive attribute, which tells MSI to treat a product with the same version as a major upgrade.

      So, AllowSameVersionUpgrades="yes" allows to build and test MSI with the same version, and previously installed app will be removed.
