Hello ,
Here is my scenario:
A higher version installer contains lower version of certain binaries . In
the higher versioned installer, sequencing "RemoveExistingProducts"
after "InstallInitialize" results in missing files. This is an issue with
Windows Installer service and has been around since 2002.
I see the following entires in the log file:
Here is a snippet from the Merlin RTM windows installer log file:
MSI (s) (48:F0) [07:39:20:997]: skipping installation of assembly component:

To solve this, i have come across the following suggestions:
-Schedule "RemoveExistingProducts" earlier in the sequence, even before
costing i.e before CostInitialize.However, doing that violates the
guidelines laid out by MSDN. MSDN suggests a sequencing between
InstallValidate and Install Initialize as one of the positions.
InstallValidate is sequenced after costing. Hence, even though this solution
might work, this is a violation of Microsoft rules
-Use REINSTALLMODE = emus
-Force the file to be always overwritten - Not feasible for Wix. Only
exists in InstallShield
-Version - Handle the versions properly in the higher versions of the
installer.
I agree that having higher versions of the files in the higher versioned
installer is the easiest and safest approach. However, there could be
genuine cases where you might want to include lower versions of certain
binaires in a highver verison of your product. This is common with third
party binaries.
So how do you think that this should be handled?
As usual, any assistance is very much appreciated.
