I am trying to reinstall some components when the user does a "Change".

The issue discussed in this thread 
http://n2.nabble.com/Always-Reinstall-a-Component-td1483743.html
is similar to my situation, but I have one extra "twist" to my problem.

My problem is that I have two features and need to set REINSTALL based on which 
of the two features are selected.

I have custom actions defined like this;
  <CustomAction Id="Both_SetREINSTALL" Property="REINSTALL" 
Value="Feat1_ReinstallDuringChange,Feat2_ReinstallDuringChange" />
  <CustomAction Id="Feat1_SetREINSTALL" Property="REINSTALL" 
Value="Feat1_ReinstallDuringChange" />
  <CustomAction Id="Feat2_SetREINSTALL" Property="REINSTALL" 
Value="Feat2_ReinstallDuringChange" />

and sequenced like this;
  <Custom Action="Both_SetREINSTALL" After="CostInitialize">!FeatureOne=3 AND 
!FeatureTwo=3 AND NOT REINSTALL</Custom>
  <Custom Action="Feat1_SetREINSTALL" After="Both_SetREINSTALL">!FeatureOne=3 
AND NOT REINSTALL </Custom>
  <Custom Action="Feat2_SetREINSTALL" After="Feat1_SetREINSTALL">!FeatureTwo=3 
AND NOT REINSTALL </Custom>

However, when I run a "Change" install, I get;
  MSI (s) (30:94) [14:38:40:428]: Skipping action: Both_SetREINSTALL (condition 
is false)
  MSI (s) (30:94) [14:38:40:428]: Skipping action: Feat1_SetREINSTALL 
(condition is false)
  MSI (s) (30:94) [14:38:40:428]: Skipping action: Feat2_SetREINSTALL 
(condition is false)

It appears that I'm in a Catch-22 here.  If I sequence my custom actions after 
CostFinalize, then my conditions work (referencing the install state of the 
features) correctly.  Unfortunately, at that point, changing REINSTALL seems to 
have no effect since the costing is complete.

Does anyone have a suggestion on how I can resolve this?

Thanks,
Dale
