RemovePreviousVersions Property
Specifies whether an installer will remove previous versions of an application during installation. If this property is set to True and an earlier version is detected at installation time, the previous version's uninstall function will be called.
The installer checks UpgradeCode and ProductCode properties to determine whether the earlier version should be removed. The UpgradeCode must be the same for both versions; the ProductCode must be different.
