Hi Jacob,
I have the experience to upgrade multiple products . Here is the wxs snippet
Insert upgrade table into product node. Do remember each upgrade item must
have its own property. In this example, OLDPRODUCT0 and OLDPRODUCT1 are used
respectively.
<Upgrade Id="C112FEB1-1111-40FA-98DC-673841526802">
<UpgradeVersion Minimum="1.0.0" Maximum="1.0.5"
IgnoreRemoveFailure="no" IncludeMinimum="yes" IncludeMaximum="no"
Property="OLDPRODUCT0" />
</Upgrade>
<Upgrade Id="91238CC3-1111-462F-9523-BC3DA0C1A4A7">
<UpgradeVersion Minimum="1.0.0" Maximum="1.0.5"
IgnoreRemoveFailure="no" IncludeMinimum="yes" IncludeMaximum="no"
Property="OLDPRODUCT1" />
</Upgrade>
Add the following to InstallExecuteSequence:
<RemoveExistingProducts After="InstallInitialize"></RemoveExistingProducts>
