Not sure if this is what you want, but what I did when I wanted to replace
either of two previous products was this (in Wix 3.0, not sure if the syntax
has changed):
<Upgrade Id='UpgradeCode-guid-for-version 3.xxx'>
<UpgradeVersion Property='PATCHFOUND' IncludeMinimum='yes'
Minimum='1.0.1'/>
</Upgrade>
<Upgrade Id='UpgradeCode-guid-for-version 4.xxx'>
<UpgradeVersion Property='PATCHFOUND' IncludeMinimum='yes'
Minimum='1.0.1'/>
</Upgrade>
<InstallExecuteSequence>
<RemoveExistingProducts After='InstallValidate'/>
</InstallExecuteSequence>
If it detects either of the specified upgrade codes then it uninstalls them
completely before installing the new version.
